I think it would be better to put those scraps on top of the pipe instead of under it.
If worms dig their tunnels under the pipe, you might be re-digging that pipe up to repair a collapse caused by worm undermining.
Worms create tunnels at that depth (only earth worms go that deep) and any weight over those tunnels could crush them, leaving an air gap between the pipe and soil.
If you have the scraps on top of the pipe, there is no possibility of harm to either the pipe or the worms, they will have a big party.
