Seki with Eyes Question 1

The explanation of Territory and Area Scoring is interesting, and I now think I almost understand the difference.
A position similar to this cropped up in one of my recent games. (Except that the game wasn't close, and was decided by resignation, so we didn't have to try to figure this out.) In this example, there are no prisoners, and White played last (both players have put down the same number of stones). Neither Black nor White can approach on the right without putting themselves in atari, so it is seki. White has an eye, and Black has an eye and a false eye... or is it really false, since White cannot approach the other end?
My impression is that this seki scores nothing for either player under Japanese rules (territory scoring), but that both players would get some points for the seki under Chinese rules and other using area scoring. Is this correct? Ignoring the seki, White has 49 and Black has 48 (no komi, no prisoners). Accounting for the seki, what is the score under area scoring? What is the score under territory scoring? Thanks, -- TakeNGive (11k) It is clearly a seki because there is a dame that neither player wants to fill. Under territory scoring the surrounded empty points in seki are not counted. White wins by 1.
Under area scoring the 3 surrounded empty points in seki are counted (2 for Black, 1 for White), and also the stones in seki (10 for Black, 10 for White). Therefore it is jigo.
Oops, sorry. I shouldn't have subtracted the difference between stones not in seki to compare the number of stones.
Area count: Therefore it is jigo.
