greymule,

I think the rule of thumb that the rulesofbaseball.com is implying is "Did interference really happen? What it successful?" If the interference didn't affect what the defense was attempting(in most cases would be an out) then no interference actually took place.

So in your two cases, neither should be called interference because in both cases outs were called on the play. So in your first case Abel scores on the bunt and in the second case place Abel on third base.
