I don't have personal experience with this behavior but that's what I've heard. I'm not sure why it is. I couldn't find any images of a cutaway body to show how the wiring is run, but I found the diagram attached below from a MAFCA seminar. If the diagram is accurate, the body is axially symmetric – so there's no reason wire 3 should fail more than wire 2.
If replacing the distributor body solves the problem, I hope the OP will run some tests with a multimeter across the contacts on the bad distributor body to see whether the #3 wire has any measurable anomalies.
