If it's true that you chose the numbers because we have ten fingers (and because of nothing else), and I can verify that, then I feel I should behave as if the event is random with probability 0.3, even if it was the 10-th digit of pi, not 10^10-th.

Yep - welcome to logical uncertainty!

I never had anything against logical uncertainty :)

The point, though, is that this setup - where I can verify Omega's honest attempt at randomness - does not produce the paradoxes. In particular, it does not allow someone to pump money out of me. And so it seems to me that I can and should "keep paying up in Counterfactual Mugging even when the logical coinflip looks as obvious as 2+2=4."
