If you get a CS undergrad, you're not likely to get in to the UPenn MCIT. It's designed for people without a CS degree. Even another tech focused degree could potentially overqualify you.
Also, the UPenn MCIT is very competitive so I wouldn't plan for a non tech degree with the goal of going on to MCIT. Too much chance and very inefficient. The MCIT is mostly for people who want to do a career change and you seem to already know what you want to do so there's no reason to do something unrelated in undergrad for a year or more with the hopes of getting into a competitive entry, accelerated master's. Focus on your plan of getting a bachelor's in IT or CS. Worry about master's after. Considering you haven't even started any college yet, I don't think your plan should be contingent on accelerating a bachelor's degree in a short time while simultaneously doing the boulder master's. I think you need to take it one step at a time. Pick a major/school: alt credits with a non competitive online school like SNHU, TESU, PUG, or go for mostly RA credits at ASU with a plan to transfer to a ranked school(you still would need to identify which ones you want to apply at) either online or in person.
