I haven't been following this discussion, so something similar may already 
have been mentioned.

The way Qt handles this is to use %1, %2 etc as placeholders. The numbers 
refer to the arguments (the order of which is obviously fixed by the 
programmer). The translator determines the order in which the placeholders 
appear in the format string.
