Even that's not set in stone, as "version" was typically used to denote takes of songs done by different stepartists. Part (number) initially seems like a good idea at a glance, until you think about the fact that the total length of the songs is relatively short in their own right.

Seems like something that might have to be checked case-by-case.

EDIT: What exactly prohibits those pieces of the song being put together in a single audio file? The length between the two submissions seems more than reasonable for a single track.
