Meaning, applying to THAT runner, not others. If it were meant to apply to all runs on the play, perhaps it would read:
No runs shall score if a "fourth out" is the result of an appeal of a base missed or left too soon on any runner who has scored.

The problem with trying that kind of contortionism is that you can do the same thing to 5.5.B. No run (singular) shall be scored ...

If they had really meant that a BR thrown out at first should erase the run scored by a runner from third, they could have written:
No runs shall be scored ...
