Default to Pages '09 when Pages '13 is also installed? Both Pages '09 and Pages '13 use "com.apple.iWork.Pages" as a bundle ID.

I can set individual .pages files to open with Pages '09, but when I try to set all .pages files to open with Pages '09, Pages '13 keeps taking over.†

† Selecting a .pages file, changing to "Pages '09", and then clicking "Change All…" always selects Pages '13. You can see it here https://vimeo.com/78545014.

Anyone know how to force OS X to accept Pages '09 as the default for all .pages files?
If Pages '09 is already open, any Pages documents you double-click will open in that app, rather than in Pages '13.

To make sure Pages'09 is always open, I added it to the list of Login items (System Preferences —&gt; Accounts —&gt; Login Items).
