Not quite.  I think that would be my perfect setup:

--8<---------------cut here---------------start------------->8---
(setq gnus-thread-sort-functions
      '(gnus-thread-sort-by-number
        gnus-thread-sort-by-date
	gnus-thread-sort-by-most-recent-date
        gnus-thread-sort-by-total-score)
      gnus-sort-gathered-threads-function 'gnus-thread-sort-by-date)
--8<---------------cut here---------------end--------------->8---

I don't really see its effect.  With
`gnus-sort-gathered-threads-function' set to the default value
`gnus-thread-sort-by-number' I get the same sorting order.

The problem is that Gnus seems to sort threads and also subthreads with
`gnus-thread-sort-functions'.  So in my case, high-score subthreads will
come before low-score subthreads, and when the score is equal,
subthreads with more recent articles will come before subthreads with
older recent articles.  But inside threads, I want sorting to be
strictly chronological from old to new.

For example, below Y should be before the subthread X, because it's
older.

I hoped that `gnus-thread-sort-functions' was applied only to thread
roots, and `gnus-sort-gathered-threads-function' to subthreads, but that
doesn't seem to be tha case.
