Elke, can you take a look at this? You know the language a bit better than me ;-)
adm1 would be the oblast (which is the iso_3166 level you mentioned). adm2 would the rayon, I'd suggest putting both in the header template and pull them onto the database. As far as I can see most of the lists are on a rayon level so this would be helpful, oblast is far to large. I will do it for some lists at uk.wp as example so we have data, then fix the scripts. If it works, they can add the missing information in the list.
Applied the patch Elke sent.
