On a more serious note, text field, `deferUpdates` and `rejectUpdatesWhileFocused` off. Value change event that fires on `browser` source only, that applies regex filter to entered value and strips unallowed items (`\D` if using java regex) or enters the max/min value if going beyond edges and writes it back to a custom property on the view. The numeric entry is bound unidirectionally to this custom property.

I think you could also use this script to send focus to the next box on 3rd digit entry.

Might still be racey or loop inducing.
