Are you sure you need the same field name "DATA" for both user and password? (just wondering — it's possible, but multi-valued fields are unusual for logins)

Also, I think you need [ ... ] around the form parameters (otherwise, the key/value pairs would end up as HTTP headers).

Why did you comment out use strict?  To get rid of the Bareword "Submit" not allowed while "strict subs" in use?  Better fix it... :) 

my $response = $lwp->post($url, [ DATA=>$USER, DATA=>$PASS, VALUE=>"Su
+bmit" ]);

Update: as for your updated node: I'd say you still need the [ ... ]
