Do you mean that you need described ones sorted prior to the new ones?
I don't think that will work trivially, but if you put the repositories
into separate sections then it should be possible.

I *think* (but have not tested) that something like this will work:

	section-sort=0
	section=Described
	section=New

	scan-path=/path/to/repos

with described repositories setting "section=Described" (the new ones
should pick up the last "section" before the "scan-path" in the global
cgitrc).
