Also, the comment following the basic rule 7.04(b), which as you point out involves a forced runner overrunning his awarded base, gives the following rationale:
"Even though two are out, the run would score on the theory that the run was forced home by the base on balls and that all the runners needed to do was proceed and touch the next base."

I think this supports J/R, because the rationale seems to fit equally well the B/R overrounding first base.

It's not that hard. If the out is made buy a runner who is forced, the run counts. B/R is not forced...timing play.
