Forgot to add the code.

#+begin_src emacs-lisp
   ;; Adapted from code posted by Paul Sexton <2011-02-16 Wed 4:51am>
   ;; - Everything now contained in one function
   ;; - Will count correct number of words inside Latex macro

   (defun org-word-count (beg end)
   (interactive "r")
   (unless mark-active
     (setf beg (point-min)
	  end (point-max)))
   (let ((wc 0)
	(latex-macro-regexp "\\\\[A-Za-z]+\\(\\[[^]]*\\]\\| 
\\){\\([^}]*\\)}"))   ; CHANGED
     (save-excursion
       (goto-char beg)
       (while (< (point) end)
         (re-search-forward "\\w+\\W*")
         (cond
          ((or (org-in-commented-line) (org-at-table-p)) ; CHANGED
           nil)
          ((looking-at org-any-link-re)
           (goto-char (match-end 0)))
          ((save-excursion
             (backward-char)
             (looking-at latex-macro-regexp))
           (goto-char (match-beginning 2))  ; CHANGED
           (setf wc (+ 2 wc)))
          (t
           (incf wc)))))
     (message (format "%d words in %s." wc
                      (if mark-active "region" "buffer")))))
#+end_src
