I'll second this statement. Offers are based on a variety of factors that show performance across the board. While your high GRE is one measure of performance and ability, your low GPA indicates perhaps a lack of focus -- an unwillingness to "stick it through" the course of a term (let alone a degree program -- and your pursuit of a MS, rather than a PhD, is perhaps also indicative of this.)
Also -- generally, in the sciences and engineering, students must find their own funding for Master's degrees... either through their workplace, or through some means such as military funding (with commitment to the military for some duration of time -- tho' this could, at my time, be done as a civilian, not necessarily as an enlisted soldier, through a program known at the time as the "Palace Knight" program). One field where I've seen in exception is if a physics student decides to pursue an M.Ed. -- or a master's in teaching, becoming certified to teach middle or high school science in the process. This is because of national incentives to increase the number of qualified science teachers in the high school.
Graduate funding is otherwise usually reserved for the students that intend to complete Ph.D. programs... that way the school gets the most "bang for their buck" by investing in a student who will be there for a longer period of time (and later be funded through research grants). The one exception, perhaps, is to get some form of funding from a school that does not offer Ph.D.'s... and perhaps offers financial incentive through some form of TA.
While you may disagree with the situation as presented to you, it is the dominate situation in the field. It's doubtful that you'll receive much special treatment for one test score, albeit above average.
