update: Hold on. I solved the problem he stated. Not the problem he had. OK, nothing cannot be solved without a bit of indirection: 
my @indicies = sort { $list[$a] cmp $list[$b] } 0..$#list;
my @rearranged;
@rearranged[@indicies] = sort @list2;

There. Make a sorted @list2 be disordered in the same way that @list is.
