(1) well, finally the following works:
(put-charset-property 'cyrillic-iso8859-5 'prefered-coding-system 'koi8-r)
i.e. instead of coding-system-put, use put-charset-property. i wonder,
why that change was needed, i.e. what changed between emacs-20.3.6 and
emacs-20.4?
(2) mm-util.el reads:
(defun mm-preferred-coding-system (charset)
;; A typo in some Emacs versions.
(or (get-charset-property charset 'prefered-coding-system)
(get-charset-property charset 'preffered-coding-system)))
in emacs-20.3, the name was prefered-coding-system, in emacs-20.4, it
was corrected: preferred-coding-system; but gnus does not check for
this name, but instead checks for preffered-coding-system, which seems
to be a typo in _gnus_, not in emacs (or is preffered-coding-system
really used somewhere?). [i.e. it seems that in mm-util.el, one should
either change preffered-coding-system to preferred-coding-system, or
add a check for preferred-coding-system].
(3) files in emacs/<version>/language/ define preferred mime charsets
for coding systems, so gnus probably could extract that info from
there instead of insisting to use such things as
put-charset-property in .emacs file.
i.e. (coding-system-get 'cyrillic-koi8 'mime-charset) returns
koi8-r.
Also, emacs/<version>/lisp/international/ contains some useful
stuff for charsets, e.g. mule-cmds.el contains
find-coding-systems-for-charsets which could be used in gnus.

i.e. gnus should find-charset-string for the message part body, then
call find-coding-systems-for-charsets, and finally select the
appropriate charset from the returned list; it could then extract the
mime-charset to use for encoding that charset via coding-system-get.
