Rumor has it that this can also mean theatrical script?

I guess technically a screenplay is different from a theatrical script?
Stutshkov puts "stsenar" next to "pyese" under category "384 fotografye, kino", and not under category "383 teater".

So I guess the nit-picking answer is no. Personally, I think a play is a play regardless of whether you're filming it or presenting it live, but then, I'm not a theater person!
