The truth is that when Gaara and the Shukaku was introduced, Mishimoto never planned on having the plot of 9 different beasts with the said number of tails. Kyuubi was well, a 9 tailed demon fox, while the Shukaku was just another beast (with 1 tail). After that, Kishimoto decided to introduce the concept of the jinchuuriki, as well as the other "tailed-beasts".

I know I've not answered your question..... but well....
