We have the same problem.
None of the scores are recorded:

We added the code in index.php and forum_index.php (to be safe) per instructions in Information (in the AdminCP) but no joy.
Any ideas?

Working now. After updating the php files, we logged out, closed the browser and logged in again... scores are working.
Cheers.
