The `add-to-list' function will place any new directory at the front of
your load path.  In general adding the new version of Org-mode to your
load path, loading or requiring org, and then calling the `org-reload'
function should be sufficient.  For more information see [1].

However, when an older version of Org-mode (e.g., one shipped with
Emacs) is loaded first it defines all Org-mode variables.  Subsequent
versions of Org-mode will not update the values of these variables as a
defvar of an existing variable does not change its value.  This
frequently leads to buggy behavior.  This point would argue for
migration of Org-mode to ELPA in future releases.
