With regard to the cloud tag badge, you do indeed have 100 points in that tag, but you haven't yet met the second requirement of 20 answers. You got those 100 points from only six answers.
From the help center:
As for Strunk & White, this one is confusing because it has some hidden restrictions. For instance, editing only tags doesn't count. I didn't take an exact count because I don't have that kind of time today, but I did glance through your history of edits and I see a number of instances where you edited the same post multiple times. That counts only once, though.
The number calculated for you in /review should be accurate, barring any bugs (I don't know of any, and only you can see this). I'm sure you will get this one soon.
