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 ()
    (org-back-to-heading t)
    (let ((beg (point)) end)
      (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))))))))
