Sorry it is an English expression meaning extra points.

The word Brownie comes from a younger group of what we call Guides or Scouts set up by Baden-Powell. I am not too sure what the equivilent is in America.
Brownies work at gaining points in different ways which enable them to progress to a badge i.e. in cookery/map reading etc.
In the context I used it, if, in a job application, you show you have done "your homework" with regard to the company you are applying to, it may make you stand out against the opposition. Hope this makes sence.
