MobileSheets does not currently modify mp3 files itself in any way. It will use the standard Microsoft framework classes to access audio file properties to read out the duration, and the duration is reported as 0 using that approach, it falls back to a library called TagLib to read the information. So I have to assume Windows must have modified the files in some way... I'm not sure how else to explain it. I will run some tests though just to confirm this.
