Hey,
Congratulations on 327. It's a great score.
What you have mentioned about projects, internships, and research papers - all are bonus points along with your great GRE score. You are looking for MS in CS and the score you got is competitive as well. For the scholarships, when you apply to the colleges they automatically consider you for the scholarship and will release the result on the decision date. Some colleges may ask for an additional essay as well and will depend on college. As for other scholarships, it will depend on your nationality as well.
Here are some of the links for your reference:

Please let us know if we can help further.
