No, as wasn't aware of them (or, I was aware of
org-mode in general, but not that it had a todo
list). Anyway that function is no good. I have
made some changes:

(defun todo-get-buffer ()
  (let*((todo-env-var "TODO_FILE")
        (todo-file     (getenv todo-env-var))
        (todo-buffer   (if todo-file (find-file-noselect todo-file t) ; NOWARN
                         (error "Set the env var %s first"
                                todo-env-var) )))
    (with-current-buffer todo-buffer
      (revert-buffer t t)) ; IGNORE-AUTO NOCONFIRM
    todo-buffer) )

(defun todo-sort-and-save ()
  (sort-lines nil ; not REVERSE
              (point-min) (point-max))
  (save-buffer) )

(defun todo (what)
  (interactive "sdo what: ")
  (let ((todo-buffer (todo-get-buffer)))
    (with-current-buffer todo-buffer
      (goto-char (point-max))
      (insert what)
      (todo-sort-and-save)
      )))

(defun todo-show-file ()
  (interactive)
  (let ((todo-buffer (todo-get-buffer)))
    (switch-to-buffer todo-buffer)
    (todo-sort-and-save)
    ))
