Yeah, that's not valid.  This should be, though:

(setq gnus-thread-sort-functions
      '((not gnus-thread-sort-by-most-recent-date)))

Note extra pairs of parentheses there, which this variable uses to mean
that `not' isn't a literal function, but a logical operator with special
meaning for sorting.

Anyway, closing this bug report...
