One problem you have with this approach is that you'll replace *any* occurrence of a state abbreviation with the full state name, without any regard of the structure of the address. For instance, 'MA Baker', who lives on "AZ Square, NYC", will not be pleased with the mangling of her address.

In fact, the OP already has state abbreviation in a variable. Which doesn't contain anything else. Just a 

    $st = $states{$st} || $st;

will do.

Oh, and why does your s/// have the /e modifier?
