The key is timing, i.e., the path to the *newest* version of Org-mode
must be at the front of the load-path before the first time Org-mode is
required.  I believe this link is the one I should have sent in my
previous email http://orgmode.org/manual/Installation.html.

Especially important is that

  (add-to-list 'load-path "~/path/to/orgdir/lisp")

is at the top of your .emacs.

I don't see where you (require 'org) below, but unless it is always done
interactively and always done after calling your load-feature function,
you're probably out of luck.

It is not about "unloading", rather the goal is to *only* load the
newest Org-mode.

Best,
