in thread Hash value sorting

Try this:

foreach my $key ( sort { $self->{_counts}->{$a} <=> $self->{_counts}->{$b} } keys %{ $self->{_counts} }

If you do $self->{_counts}{$b}, Perl thinks $self->{_counts} is a real Hash, not an HashRef. If you use the arrow to dereference, it is easier to read.

Take my advice. I don't use it anyway.
