I did some testing on the tab behaviour and this is what I believe to be true when you close and re-open Revit (2014), after you moved your ribbon tabs around.
There 2 major factors involved in ribbon tab location.
All the 3rd party tabs will place themselves before the Modify tab. If you have more than one 3rd party tab, the 3rd party tabs will order themselves in a particular order amongst themselves. The 3rd party tabs will always be side-by-side in that ordained order. I do not know what controls that order, but it is not according to the tab name
If there are more factors involved, I would like to know.

Each Revit add-in needs to create a *.addin manifest file in the addin folder, e.g. C:\ProgramData\Autodesk\Revit\Addins\2014.
In my experience, Revit loads the addins according to the alphabetical order of the name of the *.addin file.
The loading order determines the tab order.
