If all the data were numeric and limited in length, you could zero-pad it before the join and then CMP it since <=> will probably explode on longer arrays.

If you need it to be fully generic, you could always break down and make the sort block be a complex sub that loops over the elements and returns once it finds a difference.

sub sortIt { my $result = @$a <=> @$b; my $idx = $#$a; while (!$result && $idx >=0) { $result = $a->[$idx] cmp $b->[$idx]; $idx--; } return $result; }
