 I would in fact tend towards using public_transport=stop_position,
 as suggested by Dominik, given that it's already being used.

I don't think public_transport=stop_position is a particularly obvious
tag (except as part of a wider scheme), so I'd probably mention both
and see which we can persuade people to render.

I've been attempting to order a relation using P2 (I don't recommend
trying it yourself yet - the process needs streamlining). I managed to
sort the nodes in a two-directions-with-loops relation:

http://www.openstreetmap.org/browse/relation/85299

and got a reasonable line-diagram, once I'd added forward_stop and
backward_stop:

I think this confirms that line diagrams will work fine with stops
beside the way.

if I may just comment on the relation: I would start and end at the 
terminus (which seems to be The Oval) - that way the relation represents 
the longest way a passenger can travel (assuming services don't normally 
end at some point in the loop), which I think is most intuitive. I would 
also use stop rather than forward_stop and backward_stop for the 
roles since the outward and return directions of a spoon route are 
somewhat hard to tell apart. (Unless one stop in the loop is formally 
designated as the terminus where services routinely end.)

In fact - as I understand it, the tool ignores ways completely and just 
examines stop members and their order. As far as I know, retrieving the 
stops of a line on openbusmap works the same way.
