This would actually be a strong opening to a story, at least towards the mystery of why the numbers appeared, why they only track the people of that class, and when the counting actually began. Having spoken only a single-digit number of lies is almost laughable in that society.
As is, the mystery just... lingers there.
By the way, lies can be said for any reason, even good ones, perhaps especially good ones. Would POWs rather die than speak a lie? The moment means everything.
