A meaningful criterion to sort a route is so that two adjacent ways
of it share one same end node.<br>
In other words, that the route is ordered the way you travel it
without interruptions.<br>
That's what the "sort" buttons of JOSM do.<br>
And, beside finding a segment more easily, the schema of the route
made by JOSM shows the gaps (missing pieces).<br>
And in particular it will show if the road is circular.<br>
For example, if you sort the N30, you will see a gap between
Boulevard de Fraipont and Avenue de la Libération.<br>
And 16 other gaps in total.<br>
<br>
Last time I spoke of routes with a Potlatch user, he told me he
couldn't sort routes.<br>
I don't know about ID and that's quite a time ago.<br>
<br>
The N30 should be sorted and corrected.<br>
I will let Nathan do it if he's busy with it.<br>

I was doing some editing on the N30 near Liège, when I noticed
that its <br>
relation was completely unordered, with ways near the city
center being next <br>
to ways much further south (see relation `124374`).<br>
<br>
The wiki defines a relation as an *ordered list*, yet only
mentions order for <br>
bus lines. Is there a need for the road relations to be
ordered correctly?<br>
