Tried with MkII and MkIV. No small caps in sans-serif only if text is written
in english. In MkIV with gyre smallcaps are available only in normal script.
But with cyrillic no smallcaps in every case.

If you need I can test every combination and make a more detailed report.

Great! These definitions fixed the most problems. One note: previously
cyrillic "should be smallcaps" text displayed as roman, now it is missing
completely, but latin works fine. Is there a workaround to remap this somehow?
I didn't learn about typescripts enough yet to do this myself (but working on it).

Possibly this should be: \starttypescript [mono] [cursor] [name] ?

Except for missing small-caps (this is not critical at all) and with addition
of your definitions in type-otf.tex TeX Gyre support is enough to write in
Russian language (tested all fonts). I've compiled big documents and not found
any deficiencies so far.

Attached the resulting type-otf.tex. Maybe this'll save a few minutes for someone.
