“Cavemen,” a comedy that was retooled over the summer after getting crushed by critics, opened to solid numbers Tuesday night for ABC, outperforming the bows of some of fall’s other high-profile debuts.

Another new half-hour, “Carpoolers,” also clicked for the Alphabet on a night that Fox carried thanks to top-rated drama “House.” CW’s “Reaper” held up pretty well in its second week, but CBS drama “Cane” is looking shaky after its second outing.

According to “live plus same-day” DVR viewing estimates by Nielsen, “Cavemen” debuted with a 3.5 rating/10 share in adults 18-49 and 9.19 million Homo Sapiens overall, winning its slot in 18-49, 18-34 and all key male demos.

Show, based on the Geico ad campaign and featuring three cavemen trying to adapt to life in modern-day San Diego, drew a 10 share in both men and women 18-49 — a sign that ABC can still deliver male viewers despite a femme-heavy lineup.

“Cavemen” bow outdelivered Fox’s “Back to You,” the fall’s other high-profile comedy kicking off a night (earning a 3.1/10 in 18-49 in its Wednesday bow), and also topped the rookie likes of CBS’ “Kid Nation” and Fox’s “Kitchen Nightmares.” Where it goes from here, of course, will determine its long-term viability.

Coming out of “Cavemen,” “Carpoolers” followed with a similar 3.5/9 in 18-49 and 9.06 million viewers overall, placing second in 18-49 and first in 18-34. Show about four guys who commiserate about their jobs and families, built slightly on “Cavemen” among adults 18-34 and female demos.

Combined, the 18-49 delivery for “Cavemen” and “Carpoolers” was the best for regular scripted ABC series in the time period since “George Lopez” and “My Wife and Kids” in January 2005.

Also for ABC, “Dancing With the Stars” was a solid runner-up to “House” in the 9 o’clock hour (4.3/10 in 18-49, 15.90m), and “Boston Legal” picked up a bit at 10 o’clock (2.9/8 in 18-49, 10.43m), placing second.

“House” was again very strong in the 9 o’clock hour for Fox (7.2/17 in 18-49, 17.44m), standing as the night’s top program and declining a scant 8% from its huge season premiere of a week earlier. Its lead-in, “Bones,” placed third kicking off the night (3.0/8 in 18-49, 7.98m), down 9% week to week.

CBS was up over its premiere-week results on the night, but that was thanks to vets “NCIS” (slot-leading 3.6/10 in 18-49, 16.42m) and “The Unit” (3.2/8 in 18-49, 11.31m) and not rookie “Cane” (2.5/7 in 18-49, 9.19m). While “NCIS” and “The Unit” logged their best demo deliveries since March, “Cane” slid 17% from its OK premiere scores.

NBC won the night’s final hour with “Law & Order: SVU” (4.5/12 in 18-49, 11.62m), which built on its lead-in from a 90-minute “The Biggest Loser” (3.3/8 in 18-49, 7.46m). Kicking off the night, the season premiere of “The Singing Bee” finished in fourth place (2.3/7, 6.61m).

At CW, “Reaper” (1.4/3 in 18-49, 2.86m) was down modestly week to week but was again on par with its lead-in, “Beauty and the Geek” (1.3/4, 2.69m). In the net’s target demo of adults 18-34, “Reaper” built slightly on “Geek” (1.6/4 vs. 1.5/5).
