1. I do understand how multiple TIC usage works in a source routing
environment...the problem is:

When the first station attempts to contact the FEP (for example), the whole
CUR-ICR thing happens. If there are two different versions of the same
address out there, it will result in (at least) two ICR coming back. Note
that the originating switch does not realize that they are two different
TICs as opposed to one TIC coming back through two different remote switches.
The originating will choose one of the ICRs as the preferred route and the
other as the capable. My understanding is that it will test and use the
preferred route for each subsequent session to the FEP as long as it responds.
Thus, we end up the situation that "our" customers have not been willing
to accept.

Well, that is easy to fix. You as DLS can do load share for the next
circuit initiation to poke the capable route rather than preferred
one. 

Although, you are right that RFC should provide some more
criteria/suggestion on detecting similar situations.
