I can confirm that it worked on my end.  But...

here are two ways I could make the above code fail:

  1) If the buffer for the file is already open and point is after the
     text.

     It seems your code should call `(goto-char (point-min))' and, if
     you care, restore it afterwards.

  2) Your code doesn't account for hidden text in the buffer.  You could
     call `(org-show-all)'.

I suspect #2 is why you're not seeing the results you expect.
