The order of the stylesheets, afaik, is the following:
1. AddStylesheetTag2. Webblock3. Root Theme, (and other parents)4. Current Theme5. Screen6. Inline
You can try to include your CSS in the Current Theme or try to include at the end of the body using JQuery
Thanks! this is about what it looked like to me as well. JQuery it is! This is dynamically generated CSS.
