I fixed the missing commas but that made no difference.
Looks like an expl3 problem: \pdf_strcmp:D is pdfTeX's \pdfstrcmp, which might be nonexistent or available under a different name in XeTeX. This *might* get fixed by updating expl3; otherwise write to the LaTeX list ([log in to unmask], I've put it on CC).
I think I fixed this coincidentally earlier today. The update will roll out in a timely fashion.
You should be able to work around this problem by writing
\let\pdfstrcmp\strcmp
early in your preamble. If I've got this right, that is — I'm not in front of the code right now.
Hope this helps,
