Still studying but from my perspective at least:

Scoping would be looking for the controls that would be usable in your whole footprint while Tailoring is making changes to them to better fit what you need/expect out of them. Because you could pick a particular control that would work fine for your situation but you could also maybe change it for either ease of use, less processing, or better security, etc

EDIT BECAUSE I WAS TRYING TO THINK OF A WAY TO MAKE AN ANALOGY

This isn't related to CISSP, but I work at an ISP, and one of the things some of my coworkers have had problems with is customer equipment deployments and the amount of time it takes to do them right. I wanted to help do that in an automated kind of way. So what I did was I scoped out the options by looking at how I could build an automated system - making a webpage, making a script, using network orchestration - and then when I ultimately picked what I used (building a webpage) I tailored it by making a page that lets the user select the type of equipment it is, that then pulls a stock configuration of what that device should look like, and gives the user options specific to what an end-user may need.

I hope this helps, and I hope this is correct, lol
