Thanks!

This is what I use now:

(defun gnus-thread-sort-by-length (h1 h2)
  "Sort threads by the sum of all articles in the thread."
  (> (gnus-thread-total-length h1)
     (gnus-thread-total-length h2)))

(defun gnus-thread-total-length (thread)
  "Find the total number of articles in THREAD."
  (cond
   ((null thread) 0)
   ((listp thread) (length thread))))

(setq gnus-thread-sort-functions
      '(gnus-thread-sort-by-number
	gnus-thread-sort-by-articles-number))

It seems to work fine. `gnus-thread-total-length' is simpler
than `gnus-thread-total-score' but I think it does the right
thing -- please double-check.

Feel free to integrate this in Gnus if this is useful enough.

I use it when catching up on mailing lists and groups: short
threads are likely to be treated in 2 minutes, while long ones
require more attention/reading/brain.
