Sarah remarked: "An unsorted route is not wrong, it's only less precise. Maps can show it without issues including waymarkedtrails. It just can't give you some advanced features."

Just a thought, but with minimal background knowledge:-

Why not add a boolean tag, something like "sorted=yes" which editors
will always turn off unless the editor (or user) can verify that the
sorting has been maintained? Provided that there is a well defined order
relation, that should be something that editor could automate?
