Well, it seems that if you are going to use reftex in emacs 24.4.x, you
need to define some variables.  I put the following in your
org-mode-reftex-setup function:

    (setq-local tex-start-of-header "%\\*\\*start of header")
    (setq-local tex-end-of-header "%\\*\\*end of header")

immediately after loading reftex and things work better (I haven't
checked whether everything works yet).

The problem is that tex-mode assumes that it is active in a mode that
has been derived from tex-mode (such as latex-mode or plain-tex-mode)
and those modes define the variables above.  Org-mode doesn't!

This may be a change in tex-mode for the latest emacs versions?  I
cannot verify this.

Am I correct in believing that you are using emacs 24.3?
