Thanks to a bug report from Doskious on WoWI, I found out there is a small error in the zoneslib file Useful Extras, which only effects smart mounting, but for that it won't mount a flying mount there (you could easily fix it by deleting the c in "Scholazar" in that file, but I'll be releasing a fix fairly soon).

But mainly, if there are any other ruRU localization users out there besides Chiffa, it would be very helpful if you could go to Sholazar (and assuming you have a flying mount, and cold weather flight) try smart mounting and see if it mounts your flying mount. The reason being I don't know if Chiffa made those translations for it based on my misspell there, or by the correct spelling. And if it is translated off my misspell, I could use another translation for that.
