or you can use the reverse sort like this ...
@trav= reverse sort { $a <=> $b } @trav;

You're using the wrong operator. You want { $
@trav=sort { $b <=> $a } @trav;
<=> instead of cmp for numerical descending

Here is a little code :
--
my @trav= ( 1, 12, 5, 3);
@trav=sort { $b cmp $a } @trav;
foreach (@trav) {
print " $_ ";
}

After exec, we have :
5 3 12 1
But I expected :
12 5 3 1
How can I do ?
I mean easily (without developping some code) ...
