Do they just go to a queue and the next available mod selects the next available story, or are they assigned on submission to an available mod and then wait until the review process is complete?
It is not really that sequential in my experience (I was a mod years ago). If a mod is short on time, they might just look for shorter pieces rather than going in sequence if the first ones are long. Mods who are uncomfortable with certain topics might skip stories in relevant categories (I.F. being a common one). Gold/Platinum members and comp entries get priority, too.

Is there a set standard that all mods are supposed to follow or is it an individual thing?
There is not a "hard" standard unless that's changed. The problem being that there are writers from multiple countries, each with its own spelling, style, and grammar quirks. So they do what they can but inconsistencies will happen. And the mods are chosen because of their own skill as writers so their own experience will play in, too.
As with all mod-related questions, remember that these are volunteers who could be doing other things, but choose to work for the benefit of the site, not a professional editorial staff. They do a fantastic job and we appreciate the time and effort they put in.
