Hmm, first thing I thought of was a Schwartzian transform: 
my @sorted =
  map { $_->[0] }
  sort { $a->[1] <=> $b->[1] }
  map { [$_, $_->size()]} @$setarray;

Hmm, I just did a quick benchmark using an array of just three objects, and this method is slower than the original method. I'd have thought the original method would be slower due to many more method calls in the sort subroutine, vs. only three in this method. What's wrong with my thought process here?
