I don't know anything about cyrillic list schemes, so I risk having a bit of cultural embarrassment here, but the CSS3 Lists module (still in a working draft) defines quite a few types of Cyrillic alphabetical list : lower-belorussian , lower-bulgarian , lower-macedonian , lower-russian , lower-russian-full , lower-serbo-croatian , lower-ukrainian , lower-ukrainian-full , upper-belorussian , upper-bulgarian , upper-macedonian , upper-russian , upper-russian-full , upper-serbo-croatian , upper-ukrainian , upper-ukrainian-full . As expected, the support status for them is currently deplorable (of course, nothing happens in Gecko or WebKit), but, hopefully, they will move forward, they will begin to be implemented.
Update: some changes have been made - the definition of list types has been moved to the CSS3 Counter Styles module , whose current project (February 2015)), unfortunately, has lost all the alphabetical Cyrillic types. This is at the stage of the candidateโs recommendation, therefore it is unlikely that additions will be made at this point. Perhaps in CSS4 list styles?
