I'm having a hard time rationalizing why <=> did so much better than the default alphabetic sort, since it was my understanding that the latter should be better
I don't know what gave you that idea. Its a lot quicker at the hardware level to compare two integers than two strings.

As an aside, note that perl specifically optimizes  {$a cmp $b} and {$a <=> $b}, and doesn't actually call the perl code for each pair comparison
