Title: Metadata output order of fields different when batch processing

Output: inline

There seems to be a minor issue with the order of the output when you are batch processing on cli or using stay_open (ive written a simple PHP script for this).
Look at how the 'Scale Factor To 35 mm Equivalent' moves from being the 3rd item on the first run and in the second run its the 5th from last. After that it will remain the same.
Just an oddity.

This is a bit odd. I have tried hard to make the order of the Composite tags deterministic (which isn't trivial because the definitions are loaded dynamically depending on what modules have been used). Could you mail me the sample image (philharvey66 at gmail.com). I have tried with samples I have handy but can't reproduce this behaviour.

I put it on google drive to download in the previous email. Its realy not important as just just a bit odd when doing side by side comparisons.
