OP: Given that your highest score so far is 146 after some practice/study time I don't think your major problem or best solution is to do the questions in a different order. You are missing far too many for your current score range to be based on the order you do them.
You need to do something to significantly improve your understanding of what is going on with LR questions, what concepts are involved and being tested, and to change/improve your approach and skills at solving each of the questions/question types, etc.
Timing is NOT your main problem, your underlying skills are. Speed comes with/improves with better understanding of and skills with the materials. When you know what is going on with, how to properly approach the various question types, and know/understand what techniques and methods of analysis to apply to each you will be able to solve each of them in less time with better accuracy.
Other than churning through a bunch of practice tests/sections as fast as you can timed, what else have you been doing to improve your LR problem solving skills?
That's about all I've been doing. A lot of my 'skills' or 'techniques' mostly come into play for logic games. I know that I really need to improve my LR skills. Sometimes I think I can get away with it, but when I'm spending a minute and a half on a question, then yeah...I need a new angle. This, for me, is probably the hardest part of studying. I've been told that the more questions I do the more familiar the 'types' will become, and eventually that will make them easier (or faster?) to solve.
I think the thing is, whenever I finish an LR section, I don't really know how to go about reviewing it. I go back, look at all the ones I got wrong and then look at the right answer and try to figure out why that was the correct choice/why I picked the other answer instead. Is that helpful? I'm looking for thorough explanations, like the kind I get for logic games...But I can't find it, not even in the prep course I'm taking.
