You can sort the hash on the values with a snippet like this:
foreach ( sort { $urls{$a} cmp $urls{$b} } keys %urls ) {
print "$urls{$_} $_\n";
}
For more info, read perldoc -f sort.

in the replacement string).
As a style matter, you can enclose the pipe in a
chacter class with []s to make it easier to read:
