As the other replies have hinted at, the problem with ranking the rands against a random hand is that your opponent is not calling a push with a random hand. This is why intuitively you feel that A9o is better to push with than KQs; it performs better against a typical opponent's calling range. What you need to do is put your opponents on a range, then evaluate each how each hand performs against that range range. My guess is that it will be very similar to Harrington's, but might include a few more aces and/or pairs.
