I'm a computer science student and none of your WTFs are WTFs to me. 1) the numbers don't matter much, they're just what they used to rank. they don't have any implicit meaning. Texas A&M is a decent CS program so not sure why you're pointing it out. 2) maybe they didn't want to rank some schools because they didn't have much data on it. plentyo f possible reasonable explanations. 3) I've never heard of SMU (is it Southern Methodist University or Southern Michigan University or something else?) and I've heard of UMBC several times before -- they have a decent computer science program in human-computer interaction and accessibility.
