We have
(set-language-environment "Cyrillic-KOI8")

then, in the *mail* buffer with cyrillic letters,
(mm-find-charset-region (point-min) (point-max)) gives
(ascii cyrillic-iso8859-5)
(mm-find-mime-charset-region (point-min) (point-max)) gives
(iso-8859-5)

(note that current language environment is Cyrillic-KOI8, but mime
charset returned is iso-8859-5!)

After executing
(put-charset-property 'cyrillic-iso8859-5 'prefered-coding-system 'koi8-r)
we get the following results:

(mm-find-charset-region (point-min) (point-max)) gives
(ascii cyrillic-iso8859-5)
(mm-find-mime-charset-region (point-min) (point-max)) gives
(koi8-r)

So, i wonder, is gnus supposed to guess mime charset for cyrillic to
be koi8-r when the Cyrillic-KOI8 language environment is active, or i
should execute the above statement
(put-charset-property 'cyrillic-iso8859-5 'prefered-coding-system 'koi8-r)
in my .emacs?
