Unfortunately you can't scale dynamic creature models (ie you can't scale PC models) the best you can do is use one of the generic human female models, Human, Female 01 - Human, Female 12.
After you set the appearance to Invisible_Human_Female_150, go to the "Appearance" tab and set the tail to the generic human female model you want.

EDIT: Here is an example of a Solar henchman I created using this method:
