Is the following not sufficient?

#(define-markup-command (bookpart-page-number layout props) ()
    (let ((first-page-number (ly:output-def-lookup layout 'first-page-number))
          (page-number (chain-assoc-get 'page:page-number props 0)))
      (interpret-markup layout props (format "~a" (1+ (- page-number
first-page-number))))))

I use it all the time — along with some conditionals around it — and that’s 
sufficient for my needs. It doesn’t allow setting the the page-number 
arbitrarily, but I use it whenever I need the pages in each bookpart to start 
at 1 and number sequentially from there.

Hope this helps!
Kieren.

p.s. Of course, it would be great to have a much more robust and flexible 
numbering system… so maybe Harm’s code is a good beginning in that direction.
