Naturally I can't answer for the OP (and I don't know about disputed
keys) but I can report that in general this problem persists in Emacs
24.3.

On GNU Emacs 24.3.1 [1], shift select does not work in org mode. I'm not
certain this is a bug, as my understanding is that the org authors did
not design it to work with shift select?

In any case, I use a very simple workaround which makes shift select
work just fine in org mode; I've never had any problems with it. It
looks like this (Note: It is of unknown provenance, aside from the
attribution in the comment.):

;; This snippit from jisang-yoo on reddit to enable shift select in org
;; mode when cua-mode is on.
(eval-after-load "org"
    '(progn
       (eval-after-load "cua-base"
         '(progn
            (defadvice org-call-for-shift-select (before
            org-call-for-shift-select-cua activate)
              (if (and cua-mode
                       org-support-shift-select (not (use-region-p)))
                  (cua-set-mark)))))))
;; End jisang-yoo snippit

With this in my org settings, I have no problems with shift select
except that you cannot start a selection on a timestamp (because shift
with cursor keys adjusts timestamps), but I've learnt to automatically
start my selection from the end of the line above the timestamp so I
don't have any problems.

I hope this information is of some use.
