First of all, we have to remember that the sample questions were from the 4th and 8th grade, but the test he failed was 10th grade. At that age level, the questions might already be hard enough that it's justifiable to have forgotten a couple of rules and fail as an adult.
Not so much. If you follow the links you'll find up here: http://nces.ed.gov/nationsreportcard/itmrlsx/landing.aspx
Here's a sample question from the 12th grade mathematics test, specifically one marked "hard":
"The postal rate is 25 cents for the first ounce and 20 cents for each additional ounce or part of an ounce. What would it cost to mail a package that weighs 6.8 ounces?"
So in short, on top of all the other things you detail in your post which IMHO is spot on, the guy really is operating below a functional level when it comes to mathematics. Given this and those things, I'm going to go out on a limb and say he's probably not really that great at much else either.
