I've never used WWW::Mechanize, but I notice a couple things:

First, the docs say that you can use click when there's one button on the form, but the provided URL shows two buttons. Are you sure the correct button is being clicked?

Second, there are examples for WWW::Mechanize that may help you figure out how to select a radio button.

Third, you do no error checking in your script, so it's possible the code is failing somewhere. You need to check for errors. If it doesn't bite you today, it certainly will in the future...
