From http://www.mmpionline.com/ ? I was curious and searched for the test online after seeing this post. Took it, too... results look much clearer than the jumble from the copy/paste.
From what I understand, the T-scores are the ones to analyze, with the "normal" range being between 40-64. However, each different scale really needs it's own explanation, and also needs to take into consideration other factors... example; a PTSD scale considers many factors including sleep trouble, depression, other things that together are commonly found in PTSD but could be for other reasons - simply having depression while having a medical sleep problem and lack of concentration from ADHD could probably score high on PTSD but still not have PTSD. It's necessary to know what kinds of questions contributed to the score on the scale as well as a person's background to see if the score is relevant or not.
This is why an in-person professional trained in using the test is really needed to interpret it.
