Still not much response.
I think the keywords "submodule" and "fast-export" in the subject line
hit a lot of people's do-not-care filters.
I read your original two messages. It does seem like a simple ordering
problem from your description. I suspect you would get more response to
actually post your patch with a commit message explaining the problem,
and an accompanying test. And then at the very least, one outcome could
be Junio picking up the patch. :)
I think you have all of those components spread across your messages,
and just need to polish them and put them in one place.
Regarding your patch itself, your explanation make sense to me and the
goal of your patch looks reasonable. Bearing in mind that I know
virtually nothing about the innards fast-import/fast-export.
But for the patch text itself:

If you have multiple deleted entries, doesn't this leave them in a
random order at the beginning of the list? Does that matter? If they are
both 'D', should they be compared as usual? I.e.:
if (a->status != b->status) {
if (a->status == 'D')
return -1;
if (b->status == 'D')
return 1;
}
/* and now we do the rest of the function as usual... */
