Here is one way to do that - cobbled together with various bits and
pieces that I found in org.el and org-list.el. In particular, I stole
the regexp from org.el where it is used to check how to fontify the
cookie. I used the org-get-checkbox-statistics-face function as a model
for the ``(if (match-end 1) ...'' structure afterwards (all I had to
do is the (org-todo 'done) calls instead of returning a face).
The initial part limiting the region is pretty standard org code: you'll
find variations of it all over the place.
#+begin_src emacs-lisp
(add-to-list 'org-checkbox-statistics-hook (function
ndk/checkbox-list-complete))
(defun ndk/checkbox-list-complete ()
(save-excursion
(org-back-to-heading t)
(let ((beg (point)) end)
(end-of-line)
(setq end (point))
(goto-char beg)
;; check for the cookie: [100%] or [N/N]
(if (re-search-forward
"\\[\\([0-9]*%\\)\\]\\|\\[\\([0-9]*\\)/\\([0-9]*\\)\\]" end t)
(if (match-end 1)
(if (equal (match-string 1) "100%")
;; all done - do the state change
(org-todo 'done))
(if (and (> (match-end 2) (match-beginning 2))
(equal (match-string 2) (match-string 3)))
;; all done - do the state change
(org-todo 'done))))))))
#+end_src
