This is the problem with it. On one side it is said as just a weapon/device using Tesseract energy, and as a "control switch" for Tesseract. Yet Strucker and HYDRA was evidently using the Scepter in the way as to empower individuals, power which was never even speculated to be associated with Tesseract, which aslo dont makes much sense for Space Stone. Mind Stone sounds more likely for this. I prefer the luxury of doubt and wait how will this be explained :)

For your previous thing, Agent, I think that if the Scepter Gem is really a Mind Stone, Thanos msot likely possessed one Infinite Stone before New York, and handed it to Loki in hopes of acquiring Tesseract. A gamble, which he lost, as the Scpeter Gem also fell out of his hands by Avengers. But he gained Aether soon after from Collector, and wants Orb using Ronan's assistance.
