BTW, looking at p001.html, I share the concern raised by Hitch: does MakeMusic generate the SMIL files at all? I do not see any "id" associated to XHTML elements, which are needed for the sync highlighting.
What is your ebook supposed to do? Just displaying the score? The score and an <audio> player? Or should it also highlight the notes as the audio plays?
EDIT: after looking at MakeMusic web site, I think that the generated EPUB simply contains the score, not the (MIDI?) audio, and hence no SMIL at all. If this is indeed the case, removing the "media-overlay" property should fix both the two errors you reported in your first post (since media:duration is not required if there are no media overlays). As far as I can tell, the folks at MakeMusic are probably working on exporting a "better" EPUB3 (with audio and note highlighting), but in the last release they disabled this feature, forgetting to remove the "media-overlay" property (and not checking with the EPUB validator before releasing...)
EDIT 2: I edited the previous message
