Yeah, if it's a common game, chances are there are TONS of already-made scripts ready to be implemented into your site.
Alternatively, you could probably write your own by finding out how to get the server to return stats (you may end up looking at pre-made scripts to find this info) and using [man]fsockopen/man to open a connection, [man]fwrite/man to send data, and [man]fgets/man to read in data returned. Not sure though.
