FreeBSD "ports" addresses this issue by adding an "epoch" to the package
version.  The "epoch" gets incremented whenever the numbering would
otherwise appear to go backwards.  Look for PORTEPOCH in FreeBSD's
bsd.port.mk to see how they do it.  The epoch appears as the last item
in the printable package name (delimited by a comma), but sorts as the
most significant part of the version number.

For example, one would go from something like this:

	PKGVERSION=1.12
	PKGNAME=texmaker-1.12

to something like this:

	PKGVERSION=1.2
	PKGEPOCH=1	# numbering went backwards from 1.12 to 1.2
	PKGNAME=texmaker-1.2,1
