I'm attempting to create the function
gnus-thread-sort-by-average-score (to deal with those threads that
rocket to the top of the total-score sort because the couple of articles
I read ballooned into a monster thread of 50 kazillon postings) as follows:
(defun gnus-thread-sort-by-average-score (h1 h2)
"Sort threads by the average of all scores in the thread.
Unscored articles will be counted as having a score of zero."
(>
( / (gnus-thread-total-score h1)
(gnus-summary-number-of-articles-in-thread h1))
( / (gnus-thread-total-score h2)
(gnus-summary-number-of-articles-in-thread h2))))
Problem is, while gnus-thread-total-score returns the score,
gnus-summary-number-of-articles-in-thread is returning zero! What am I
doing wrong here?

You could also use
gnus-thread-sort-by-total-score
and then set
gnus-thread-score-function
to some function taking the average.
E.g:
(defun arithmetic-average (&rest numbers)
(/ (apply '+ numbers) (length numbers)))
(setq gnus-thread-score-function 'arithmetic-average)

That won't work, because arithmetic-average won't get passed the
entire list of scores, but the score of the parent and its sub-threads:
---
gnus-thread-score-function's value is +
Documentation:
*Function used for calculating the total score of a thread.
The function is called with the scores of the article and each
subthread and should then return the score of the thread.
---
This means that if there is a subthread of 20 articles averaging
5 (total 100), a subthread of 2 articles averaging 50 (100), and a
parent of 100, arithmetic-average would return 32 instead of 13.
