The culprit is an <ol> tag which resumes from an earlier section so needs to start counting from 7. I'd prefer my book to validate correctly, but I wonder if this might be an oversight in the validator. Is epubcheck correct in telling me that 2.0.1 era epubs are not capable of using custom list numbering? None of the various ebook readers I've tried (including Calibre) appear upset by the glitch, and I'm wondering if it even IS an error.

IIRC somewhere on the IDPF pages there was a list of what tags/attributes are permissible in which epub version, but of course I can't find it right now
Yes, that's correct about ePub 2. You can try ePub 3 and see what happens.
