Wireshark is software, not a human being, and thus cannot itself generate a mean opinion score; the same applies to any other software.

The mean opinion score is calculated based on *subjective* evaluations of sound quality by human listeners; see the Wikipedia article:

	http://en.wikipedia.org/wiki/Mean_opinion_score

and the ITU-T recommendation to which it refers, P.80:

You could, at best, have Wireshark play back the audio and have various listeners evaluate it, and then calculate the MOS based on their evaluations.
