Are there any members here that work for TSA? I have noticed that what draws extra attention varies from airport to airport. For example, when I travel it is usually under military orders which I present at check in. Airlines, such as United, tell me that I am exempt from extra screening by TSA but I normally get the special treatment anyway. Don't get me wrong, I'm not complaining, if thats what they feel they need to do to keep everyone safe I'll gladly put up with the extra hassle. I think what happened to you was miscommunication or misunderstanding between TSA requirements and the airline. If you would have shown up under a different shift they may have allowed your ride to fly. I'm not an expert on this so don't quote this as gospel. Zandor is right, next time ship it to a friend a couple of days before you fly.
