That's because bulgarian default language module only knows the
cyrillic letters and does the right thing for them (disregarding
letter case in indexes and glossaries is the usual thing to do). It
doesn't know anything about latin letters -- after all, they don't
exist in bulgarian script, AFAIU -- and just places them at the start. 
Just like all other non-letter characters, e.g. "!" or "/" would come
out at the start.

A predefined language module for your use case does not exist; the
sort order between cyrillic and latin letters is not defined in any
general way. And frankly, you will not be able to get results within a
few minutes.
