A similar approach, but likely slower due to more levels of indirection: 
>perl -wMstrict -le
"sub ascending  {   $a cmp $b   }
 sub descending { - ascending() }
 my @ra = qw(q w e r t y u i o p);
 my $sorter = 'descending';
 @ra = sort $sorter @ra;
 print qq{@ra};
 $sorter = 'ascending';
 @ra = sort $sorter @ra;
 print qq{@ra};
"
y w u t r q p o i e
e i o p q r t u w y
