NBC continued to lead CBS and ABC in the prime-time race after six weeks, taking Week Six handily with a 17.5 rating and a 27 percent audience share, compared with a 16.7/26 for CBS and a 15.3/24 for ABC . . . . . .
Two of NBC's new series, "Amazing Stories" and "The Golden Girls," finished in the Top 20, as did ABC's new "Growing Pains," almost surely this year's first runner-up to "Trapper John, M.D." in the annual race for the Positioning Is Everything In This Business And Don't You Forget It When Contract Renewal Time Rolls Around Trophy . . .
Checking the performance of other new fall season series entries, NBC's "227" (another definite Trophy contender) was 27th last week. ABC's "Spenser: For Hire" (an early favorite for the 1985-86 Lazarus Award) climbed to a tie for 41st in its first outing since escaping from Friday to Tuesday. NBC's "Hell Town" was 45th . . .
ABC's "MacGyver" tied for 46th, CBS' "The Equalizer" was 49th and CBS' "Twilight Zone" finished in a four-way tie for 55th that also included NBC's "Misfits of Science" . . .
ABC's "The Insiders" was 60th and CBS' "Charlie & Company" was 62nd . . .
Both CBS' "George Burns Comedy Week" anthology, in 62nd, and ABC's "Hollywood Beat," 67th, made the Final And Usually Fatal Five . . .
The Five also included the ABC movie "The Midnight Hour," in 64th; followed by NBC's "Silver Spoons"; and the umptyumpth rerun of "Goldfinger" on ABC, which finished 66th, just short of last place for the week ending Nov. 3 . . .
In other highlights, a Garfield Halloween special on CBS was 32nd; CBS' Tuesday movie, "Into Thin Air," was 37th; the San Diego-L.A. Raiders NFL game on ABC tied for 38th; and CBS' Saturday movie, "Badge of the Assassin," was 51st . . . Also in the News
Patty Duke was named the winner yesterday of a hotly contested election for the presidency of the 58,000-member Screen Actors Guild . . . Duke, who received strong support from outgoing president Ed Asner, defeated Ed Nelson, who was backed by Charlton Heston, 10,838 to 7,419 . . .
Asner won a seat on the 99-member board of directors, with 4,811 votes, second to Robert Guillaume, the "Benson" star, who received 5,131 . . . There were 13 openings in the Hollywood section of the board, and Duke's supporters won 10 of them . . .
The campaign focused more on the long-standing differences between the forces of the liberal Asner and the conservative Heston than on Duke and Nelson . . .
The seventh annual National Commission on Working Women broadcast awards will be presented today at a Capital Hilton lunch- eon . . .
Winners get an "Alice," named for the working heroine of the one-time CBS series. A total of 35 Alices will be awarded in 10 major categories (in both TV and radio), including public affairs programming, documentaries, news series, entertainment, editorials and (a new category) children's programming . . .
Linda Lavin, the original "Alice," and Betty Thomas, who plays Sgt. Lucille Bates on "Hill Street Blues," will be the presenters at the noontime luncheon, which will be preceded by a reception that gets under way at 11 a.m. . . .
Marilyn Beck reports that Joan Collins, after making noises earlier this fall about leaving ABC's "Dynasty," has quietly signed a new contract that gives her a salary equal to that of costars John Forsythe and Linda Evans . . .
The trades have estimated that Forsythe and Evans get about $70,000 an episode, or $2.1 million a year . . .
"CBS Evening News With Dan Rather" won the network news race again last week with a 13.5 Nielsen rating and a 23 percent audience share . . .
"NBC Nightly News With Tom Brokaw" was second with a 12.4/22 and "ABC World News Tonight With Peter Jennings" was third at 11.5/20 . . .
Total viewership for the network news shows in the first week of the fall without daylight savings time was about 22.2 million TV homes, up by 4 million homes over the previous week . . .
The 22 share for NBC was that program's highest since the week ending Dec. 31, 1982, and the rating was its highest since the week ending Feb. 1 of this year . . .
NBC News, by the way, is really pushing Tom Brokaw to the front these days in an effort to secure a strong position as number two and perhaps even mount an attack on CBS . . .
During the November ratings sweeps, Brokaw is doing the nightly 8:58 p.m. News Digests, and last Sunday he anchored "Meet the Press" as Marvin Kalb accompanied Secretary of State George Shultz on this week's trip to the Soviet Union . . .
In addition, "Nightly News" has adjusted its format to permit more "cross-talk" between Brokaw and correspondents and more live interviews conducted by the anchor . . .
In another departure for NBC, "Nightly News" plans to devote about half of its 23-minute Friday night broadcast to the Philippines and has similar projects in the works . . .
Speaking of news digests -- and we were, just three paragraphs ago -- poor Peter Jennings thought he was taping yesterday's 2:58 p.m. news cut-in for the ABC network. So when he referred to the secretary of state as "Secretary of Shultz" he put his head down on the desk in shame, as news anchors always do when they make a mistake on tape. Peter, however, was live . . .
