Sorry, my fault. Forgot to move point forward after matching a link.
I pushed this fixed version to Worg:

#+begin_src emacs-lisp
  (defun dmaus/org-check-percent-escapes ()
    "*Check buffer for possibly problematic old link escapes."
    (interactive)
    (when (eq major-mode 'org-mode)
      (let ((old-escapes '("%20" "%5B" "%5D" "%E0" "%E2" "%E7" "%E8" "%E9"
                           "%EA" "%EE" "%F4" "%F9" "%FB" "%3B" "%3D" "%2B")))
        (unless (boundp 'warning-suppress-types)
          (setq warning-suppress-types nil))
        (widen)
        (show-all)
        (goto-char (point-min))
        (while (re-search-forward org-any-link-re nil t)
          (let ((end (match-end 0)))
            (goto-char (match-beginning 0))
            (while (re-search-forward "%[0-9a-zA-Z]\\{2\\}" end t)
              (let ((escape (match-string-no-properties 0)))
                (unless (member (upcase escape) old-escapes)
                  (warn "Found unknown percent escape sequence %s at buffer %s, position %d"
                        escape
                        (buffer-name)
                        (- (point) 3)))))
            (goto-char end))))))
#+end_src
