You just need to add org as an org babel language:

  (let (ob-lang-alist)
    (add-to-list 'ob-lang-alist '(org . t))
    (org-babel-do-load-languages 'org-babel-load-languages ob-lang-alist))

You don't necessarily need the let form above, but that is in a form that
allows easily adding more languages in future.
