I added my draft to the OSM wiki: http://wiki.openstreetmap.org/wiki/User:Rurseekatze/Station_Importance_Draft.

In this version of the draft, I removed all that international stuff, as this is problematic like you described here. Instead I used terms that refer more to geographic distances and the train network than to boundaries.
