comment How do you determine the order of tasks in a usability test?
For each participant. The idea is to see if doing task A makes task B more/less usable. To do that you need to have different ordering for different participants.

comment Who should be responsible for A/B testing and conversion optimization?
I agree that having random folk doing random tests is a bad idea. I disagree that having a single individual/team be solely responsible is the only way to stop that happening.

If you're talking about the thing at 2:30 all they're doing is looking for runs of the same number across several questions (somebody went down the test and marked everything "4" — or whatever. I'd personally be a little suspicious of that as a good metric since I've seen genuine folk do that…

I think you're mis-reading the intent. They're not pairs of questions that are asking the same thing in two different ways. It's alternating questions so that on one the "high" is agreement and on others the "high" is on disagreement with the idea that it would encourage the participant to read each Q in detail. This was good practice at the time SUS was created, but there's been more recent research that it can actually lead to more user errors. There's actually an 'all positive' version of SUS out there measuringu.com/positive-negative.php

UX is a darn broad field. Can you talk about what the focus of role you're looking for? Research? IxD? Graphic Design? Usability Testing? IA? etc.
