> <snip> I personally think that the wand chose him over Draco, who
had Disarmed DD and become its master (also without ever touching it)
during the final confrontation with Voldemort, when he informed the
wand that its master had been Disarmed. <and a number of other
reasons, too>

hp_fan_2008:
My theory is that the wand recognized Hary as the owner of the wand
which was used to disarm Dumbledore. It could have recognized the fact
when Voldemort tried to murder Harry in the Forest. This would explain
why the Cruciatus Curse didn't work on Harry.
