I think the second example should be:
foreach(sort {$hash{$a} cmp $hash{$b}} keys %hash){
do something...
}
Notice the %hash (and not $hash) at the end.

You can use the longer form of sort for this. You may have seen this
before:
my @array = sort {$a cmp $b} @unsorted;
#$a and $b are default variables for the sort command.
#to reverse sort, you can reverse $a and $b.
You can also do this:
foreach(sort {$hash{$a} cmp $hash{$b}} keys $hash){
do something...
}
which I think is what you want.

Subject: Hash Sorting?
Hello all......
Does anyone know how to sort a hash in ascending order on the value?
If possible, a little example!
Thanks,
Kurtis
