I had the same problem as you (MBA same specs only 4 months old) and I found the solution on Apple's discussion forums. You need to download iTunes 12.0.1 and install it manually. Afterwards run update again and the little red 1 will disappear. For some reason the version I had was 12.0.0.140 and it would not update even I had four instances of the update in history.
I tried to download it from Apple but I had problems with it saying "thank you for downloading" and nothing ever downloaded. I found another one on TechSpot's website.
