Orion was established to be below Infinity man even back then. And he never encountered the gravi guards directly.However, your example does have some merit in regards to Infinity Man, given that he was able to nullify their powers and IM's power source is... the source/ALE. The same power source the mother box taps into, and it has shown the capability to tap into the ALE although only in direct contact (with those mortals that had it in their heads).
It's not conclusive of anything of course but it is an interesting example worth mentioning.
And all you had to is ask. 🙂
Im assuming you are familiar with his thunderbolts feats? so i won't have to post them.

Now with thor: https://imgur.com/qLUE2bb
He also easily lifted a city-sized chunk of the earth: https://imgur.com/1zJwwCD
And put a shield which no one could pierce: https://imgur.com/4eMKAX8
Now with the WCA: https://imgur.com/a/zV6VsGe https://imgur.com/a/yWZbJXS
He was KO'd due to a drug administered to him beforehand.

He could also control light waves, btw (which technically shouldn't be affected by gravity unless the writer had relativity taken into account which makes his gravitational powers all the more impressive): https://imgur.com/r8s7Swz
We get an idea of the extend of his powers where we see him increase his own mass/density into infinity becoming a singularity/black hole (technically he's done this multiple times but it was only this time that he did intentionally -- increased his mass to infinity -- as opposed to the other times where he simply lost control): https://imgur.com/a/DxdwiuF
Recently though he's been watered down a bit, when he re-appeared as being part of AIM's council he said that he regenerated from mere atoms: https://imgur.com/FSJjRP9
Takes apart unity squad: https://imgur.com/a/DUREk6i
Puts up a shield which avengers/unity squad couldn't break (including jane thor): https://imgur.com/a/8GKOZzm
Although naturally, Quasar (Avril) was able to break it single handedly since she has a thing for shields.
