I had a similar project awhile back. I had pulled ip addresses from my apache access log and wanted to see how many times a certain ip hit our web site. Basically I used the ip addresses as the hash keys and the value was incremented for each instance. Everyone told me I could not sort by the values (sounds like you want to do the same thing here). I did notice in the perl cookbook something that worked in sorting the values... sorta :-) Long story shore, I was able to sort / print the values in order. Worked great! Here is the sorting of the hash I used. Hopefully this will help: 

# This section will count the number of times we see an ip address
 
open ACCESSLISTIPS, "access_log_ips"
        or die "The file could not be opened ($!)";
 
        chomp(@ips = <ACCESSLISTIPS>);
        foreach $ip (@ips) {
        $count{$ip} += 1;
}
 
# This routine will sort the values of a hash then print them out for 
+us.
#
        foreach $ip (sort { $count{$a} cmp $count{$b} }
                keys %count)
{
        print "$ip was seen $count{$ip} times.\n";
}
