So, I got around to checking on those files a bit sooner than I thought I would and found that like the .mobi format (which isn't editable) the .azw3 format (which is) uses the side-along .apnx file to mark page numbers. Further, if you open an .azw3 file to edit it, there is nothing in the file that marks the pagination. Amazon must have some other way of producing the .apnx file. Obviously at some point someone has to match places in the text with the beginnings of pages to produce the .apnx file, but that work is not done in the .azw3 file (or if it is, it's stripped out by amazon before the book ships or by calibre when it opens the book for editing).
So, I think I'm back to my original plan (manually mark the page breaks in the text and then use a modified apnx.py to create the side-along file).
On a related note, I've noticed that apnx.py only works on .mobi formats, not .azw3. So making this work will also involve modifying it to accept a new format.
