sorting an array of hashes

bsmithsweeney has asked for the wisdom of the Perl Monks concerning the following question:

Hey all,

I have an array of hashes similar to the following structure (but with a lot more records):

@ip_address = (
    {
       IP=> "127.0.0.1",
        COUNT => 2,
    },
     {
        IP => "192.168.0.1",
        COUNT => 5,
    },
);

I'd like to sort this array based on the numerical value of COUNT. I'm sure I need to use the keys function here, but passing that to sort in the proper manner is a bit of a head-scratcher to me. Any suggestions are appreciated! Thanks in advance-
