The quiz module implements hook_user_cancel() but not hook_user_delete(). As a result user's results are deleted only when the user is cancelled, not when the user is deleted.
See the documentation of hook_user_cancel:

This hook is NOT invoked for the 'user_cancel_delete' account cancellation method. To react on this method, implement hook_user_delete() instead.
