I think we both misread his question -- here is what I missed: Unique items are only line per line, and he wants to sort on one coulumn and then if a "tie" happens break it with second sort on another coulmn.
I am trying to think of a good way to do this.
Edited this should work as long as both are the same type:
@data = numeric_sorter(2,4, @data)
sub numeric_sorter {
my ($field_num, $field_num_secondary, @data) = @_;
my @sorted_items = sort {
if ($a->[$field_num] != $b->[$field_num]) {
$a->[$field_num] <=> $b->[$field_num]
} else {
$a->[$field_num_secondary] <=> $b->[$field_num_secondary] }} @data;
return @sorted_items;
}
