7-card stud/8 trivia question

Try to find the answer to this question in any poker book!  In 7-card stud 8 or better which of the following two hands would win the low half of the pot?  A-A-5-6-7 or 2-2 5-6-7 ?  I contend that the former would win because aces swing but my fellow players say no.  One day at Foxwoods, during an Omaha/8 tourney in the grand ballroom, I asked Men'the master' Ngyuen, who was in the middle of the room trying to get noticed.  He did not answer instantaneously but did finally concur with me.  I finally found printed confirmation in a slim poker book entitled Poker is the Name of the Game by Walter Gibson (page 84.)
