You need to move the more general match "^nnimap\\+Fastmail:INBOX" to
the end of the list:

(setq gnus-parameters
      '(("^nnimap\\+Fastmail:INBOX\\.D-BARF$"
         (to-address . "D-BARF@yahoogroups.de")
         (subscribed . t)
         (gnus-use-scoring t)
         (gcc-self . "nnimap+Fastmail:INBOX.Sent Items"))
        ;; [...]
	("^nnimap\\+Fastmail:INBOX"
         (gnus-use-scoring nil)
         (gcc-self . t))))

The difference is that `gnus-use-scoring' is a group local variable,
whereas `gcc-self' is a group parameter (dotted list).  Surprisingly,
they behave different:

(setq gnus-parameters
      '(("^nnimap\\+.*:INBOX"
	 (tmp-variable 11)
	 (display . 11))
        ("^nnimap\\+.*:INBOX\\.test$"
	 (tmp-variable 22)
	 (display . 22))))

When I enter INBOX.test `M-: tmp-variable RET' returns 22 whereas 
`M-: (gnus-group-find-parameter gnus-newsgroup-name 'display) RET'
returns 11.

I think this inconsistent behavior should be fixed.  IMHO it would be
better if we choose the same behavior `gnus-posting-styles'.

Bye, Reiner.
