Well, I see that you are thinking of the release numbers as decimal. I'm not sure if this is really common. (e.g 2.4.9 is lower than 2.4.10 in linux world)
which is true. but i feel somehow (and i think i have seen it, even in linux world), that the successor of 0.99 is rather 1.0 than 0.100
anyhow, i think the argument with "big changes" might be a better one, as it is really more than just the successor of 0.87, and skipping single version numbers (like 0.90) seems even worse. and 0.888 is such a beautiful number
