Infield fly batter out, I on B/R prevents DP on R1 for 2nd out, and TP on R3 for 3rd out.

Please quote the rule for me in baseball that would not allow a run that scored before any interference?

There is no leaving early penalty if a fly ball is not caught, infield fly rule or not.
No out can be recorded in either circumstance for that, regardless of the interference.

So the question is does the interference negate the run? What rule in baseball covers that?
