I've seen a few knife scales done cross grain, but personally I don't like seeing it, suppose that's cos I'm a carpenter for a living. We tend to try and hide any cut ends on second fix (the bits that show) items if we can.
If they are glued to something else structural they would be fine but Peasant knife scales need a little flexibility and short grain won't have the required strength.
