Thanks. I really appreciate your help.
Here is how I failed: 
@id = sort { $lid->{split(/=/, $a)} cmp $lid->{split(/=/, $b)} } @id;

Your approach doesn't seem to sort the array unless I change it from 
my $a_ = $a
my $b_ = $b

[download]
to 
$a = $a
$b = $b

But if I do that then the values of the array get cut off at the '=' sign (I understand why).
What does the 'my $a_ = $a' do?
