I'm not sure about that. I heard people even use git to keep their
accounting history. And there have been requests in the past to do
deterministic sorting before writing out the data to xml. I seem to
remember this was mostly done.
There was also a bug report recently about an odd case where two
transactions swapped each time after a save. Still this suggests that
ordered save seems to be the default.
To be sure you can easily run a couple tests yourself.

Unfortunately I'm not aware of any.
