Is something up with my counting?

In a recent game over on the Dragon Go Server in which I had black, we reached the following position:
I logged in to DGS to play my next move, Black 233, and was surprised to see that for White 232, White... resigned, saying "Thanks, I counted."
I had been counting too, and was convinced I was behind. There are two big sekis in the top right and bottom left, but beyond that, White has:
2 prisoners already
12 points in the lower right
16 points in the center plus two prisoners
21 points on the left
6.5 points komi
For a total of 59.5 give or take depending on how we both handle the endgame.
Black has:
1 prisoner already
7 points on the left
12 points on the top
30 points on the right plus two prisoners
Any way I count it, Black is behind by several points.
So I fired up Cgoban, and the results were shocking. It said White was ahead by 18.5, except that this included all the stones in the bottom left which it claimed were dead; take that territory away from White and Black should theoretically be leading. I played out the seki on the bottom left and the score changed wildly.
So what's going on with this game (other than the fact that it's over now)?
I seem to be having difficulty getting the diagram to show properly and can't open the "How to make a diagram" thread, so if it doesn't show up, here's the SGF:
I'm not particularly looking for a review here, since I haven't gone over the rest of the game. I do have a feeling we both screwed up the corners that wound up sekis, however.
