Comparing names to check that its not a player using a command block and @a or @p returns incorrect results

I just setup my server using vanilla because I have had endless issues making bukkit work for me. Since the advent of command blocks vanilla has become almost all I need - multiworld/world teleport command. Aside from that I decided to use the scoreboard system to be a almost permissions system with command blocks. I wanted to protect my house with a command block setup where you enter adventure mode. Except that would effect me too and I need to mine for resources. So I decided to make it exempt me. Upon trying to do that though, I ended up with a strange result of my player name (the name that was being filtered) and all the other players - a seemingly random player although it was the same person every time. Such as "myname, player3" without player2. I am positive that I am using the right format as I have tried every single format and multiple commands as well. As an aside, where am I supposed to request a feature (there are too many places where this is an option)?
