I was making a general point. With the sort function as you give it, there's still a difference, as shown by: 
$ perl -wle'use overload q!""!=>sub{0},fallback=>1; $x=bless[0]; $y=bl
+ess[1];
print map @$_, sort { $b <=> $a or $b cmp $a } $x, $y;
print map @$_, reverse sort { $a <=> $b or $a cmp $b } $x, $y'
