Adaptive scoring doesn't work

[Guilherme Mesquita Gondim]

I have this settings in my ~/.gnus:

(setq gnus-default-adaptive-score-alist
               '((gnus-unread-mark)
                 (gnus-ticked-mark (from 4))
                 (gnus-dormant-mark (from 5))
                 (gnus-del-mark (from -4) (subject -1))
                 (gnus-read-mark (from 4) (subject 2))
                 (gnus-expirable-mark (from -1) (subject -1))
                 (gnus-killed-mark (from -1) (subject -3))
                 (gnus-kill-file-mark)
                 (gnus-ancient-mark)
                 (gnus-low-score-mark)
                 (gnus-catchup-mark (from -1) (subject -1))))

(setq gnus-parameters
      '(("mail\\..*"
         (gnus-use-adaptive-scoring nil))
        ("gmane\\..*"
         (gnus-use-adaptive-scoring t))))

But these settings in gnus-parameters doesn't work, others settings it works
properly. 

If I do:

  (setq gnus-use-adaptive-scoring t)

The adaptive scoring works, but for all groups. :-/

        
Can anyone help me with this? :-D

Thanks,
