Following the tagging recommendation of http://wiki.openstreetmap.org/wiki/Key:cycleway, I've tagged a few one-way streets in Lausanne with contraflow cycle lanes using the tag cycleway:right=opposite_lane. Unfortunately, it seems that routing.osm.chdoesn't understand this, as illustrated by the following route suggestion:

Are you sure about cycleway:right? If I understand the wiki page correctly, right/left are meant relative to the direction of the way. From aerial pictures that looks like a cycleway:left.

Indeed, instead of doing a V, it is possible to go straight on the Chemin Antoine-de-Chandieu by bike, as there is a contraflow cycle lane, which I've tagged as such.

What is the proposed solution? Should I change my tagging to the (apparently more frequent) cycleway=opposite_lane? Should routing.osm.ch be changed to understand cycleway:right (and :left)?

I was about to say that I find it a little bit redundant because it should be fairly rare that the cycle lane does not follow the usual rules for right or left handside dirving. But thinking about it further there is some merit in tagging something like

cycleway:left=opposite_lane cycleway:right=track

Not that we do a lot of this kind of side-specific cycleway tagging at the moment but nothing wrong with being ready for it. So, I'm ok with changing the routing profile. I'll have a look at it as soon as I find a minute.
