The route is pretty convoluted, but the idea is to do missions that have as few enemies as possible first, then save others for later after getting upgrades.
Missions are listed in reverse order just so more difficult missions are done first, but it makes no difference what order you do the missions as long as you do them all in that portion.
There is some flexibility with the route; after getting Dark Blade you can do the remaining missions in pretty much any order you want (with the exception of Foreman, of course).
