Well, here's one way to get those page references, using filters:

(defun my-odt-filter-pagerefs (text backend info)
       "Make page references, not textual references in ODT export."
       (when (org-export-derived-backend-p backend 'odt)
             (replace-regexp-in-string "text:reference-format=\"text\"" "text:reference-format=\"page\"" text)))

(add-to-list 'org-export-filter-link-functions
                  'my-odt-filter-pagerefs)

(Whee! I just wrote my first export filter.)

Org doesn't know what the page number will be, so when you open the
document in e.g. LibreOffice, you still have to update fields (Tools >
Update) before you see page numbers.
