As I know PanoCube ( or to be more precise PanoTools ) use the same compression scale form 1 (worst quality, large compression) to 100 (best quality, low compression). But unlike "all other software" you mentioned above it gives to user 100 quality steps but not only four. You have more space to play. More over it could compress different tiles with own compresion rate. What's bad?

Perhaps your CubicConverter is bugged. I have checked all tiles with proffesional JPEG explorer tool and it says: 90% 90% 90% 90% 90% 80% (5 tiles with nearly "Best" compression and 1 tile with nearly "High" according to your prefered four steps quality system). Guess CubicConverter simply confused because of different tiles compression used.
> If I recompress it with a setting of 90% you get a movie size 4200 kb
As I wrote above Bernhard also used 90% and got only 2856 kb.

Interesting to see your samples ;-)
