The cookbook procedure (by Richard Light, but making that information
appear in the HTML is something I need to fix) is meant for numbering
elements in a way that cuts across the hierarchy.  What you want is to
number elements in a way that reflects the hierarchy, and for that you
can use hierarchical-number-recursive, but there isn't an example in
the Cookbook.

Try this:

(element (DIV TITLE)
	 (make paragraph
		 (let loop ((hierarchy-list
		   (if (null? hierarchy-list)
		       (let ((item-number (car hierarchy-list)))
			  (format-number item-number "1")
			  (loop (cdr hierarchy-list))))))
		" "))
