C-h v gnus-score-find-score-files-function:

[...]

This variable can also be a list of functions to be called.  Each
function is given the group name as argument and should either return
a list of score files, or a list of score alists.

[...]

"Score alist" means the form found in .SCORE files, right?
Like:

(((and ("from" "foo" s) ("subject" "bar" s)) -100))

And a list of those would be:

((((and ("from" "foo" s) ("subject" "bar" s)) -100)))

OK, let's try it:

(setq gnus-score-find-score-files-function
      `(,(lambda (group)
           `((((and
                ("from" "foo" s)
                ("subject" "bar" s)) 
               -100))))
        gnus-score-find-bnews))

Select a group => Wrong type argument: listp, -100.

Gnus wants another level of parens around the score alist:

(setq gnus-score-find-score-files-function
      `(,(lambda (group)
           `(((((and
                 ("from" "foo" s)
                 ("subject" "bar" s)) 
                -100)))))
        gnus-score-find-bnews))

works, but this isn't what the documentation says.  Or am I dreaming?
