The short answer is, there is no code that attempts or guarantees to
sort the headers in a new message. The current ordering results from
code in `message-mail', where a header list containing "To" and
"Subject" is passed down, ultimately to `message-setup-1', which does
the actual header insertion (see the comment ";; Insert all the
headers").
The weird thing is that `message-sort-headers' is called before
*sending* a message, in `message-send' -> `message-fix-before-sending'.
Why sort order matters for an outgoing message I don't know.
Anyway, if I were you I would add `message-sort-headers' to the
`gnus-message-setup-hook', or if you don't want it to be gnus-specific,
to the `message-header-setup-hook', with a higher DEPTH argument.
HTH,
Eric
