This should work, although its a bit funny (you can wrap it in an
interactive command like above):

#+begin_src emacs-lisp
  (with-current-buffer "my.org"
    (eval (append (list '+)
                  (org-map-entries
                   (lambda () (if (eq (org-outline-level) 1) 1 0))))))
#+end_src

or rather something like this:

#+begin_src emacs-lisp
  (with-current-buffer "my.org"
    (let ((count 0))
      (goto-char (point-min))
      (while (re-search-forward "^\\* " nil 'noerror)
        (setq count (1+ count)))
      count))
#+end_src

cheers,
