As per the Help section:

If you are an experienced Stack Exchange network user with 200 or more reputation on at least one site, you will receive a starting +100 reputation bonus to get you past basic new user restrictions. This will happen automatically on all current Stack Exchange sites where you have an account, and on any other Stack Exchange sites at the time you log in.

Basically, you only get the +100 bonus points if you have 200+ points on ANOTHER StackExchange network site.

According to your profile, you are only active on Drupal Answers, so you don't qualify for the "bonus" points.
