I don't see how a lambda would be needed.  Here's an example from
the sorting section of the info documentation.  

     (setq gnus-thread-sort-functions
           '(gnus-thread-sort-by-number
             gnus-thread-sort-by-subject
             (not gnus-thread-sort-by-total-score)))

The same construct works for gnus-article-sort-functions too.

Following your reasoning, one should add reversed versions of all the
gnus-article-sort* and gnus-thread-sort* functions, but we don't do
this because we have a general purpose way to specify reversed
sorting.

Or am I misunderstanding what your function would be used for?
