Thank you for your post.
Our Development and Testing teams are aware of this issue, and it was changed in FileMaker Pro 13 to reflect the correct order.
This will not be changed in FileMaker Pro 12.
That exactly matches my expectations. Just wanted to add this to the list as the "fix" had triggered a thread over in the FM Pro Forum section when a user's value lists changed after upgrading to v13.
