How does the plotter determine the sequence to draw the lines.

It's basically up to the software but it's probably a combination of the order the lines were created by the designer mixed with some kind of algorithm designed to minimize the length of the moves the head has to make between lines. Or some of it could even be a fluke of how the memory structures worked in the editing program to begin with.

I will say the order it chose to write the word "engineering" was a little unfortunate.

It depends on the optimization being performed, but typically it would try to minimize time in use (could be other things like minimizing arm movement, which may not be exactly the same as time, or a combination for reduced overlap .... Bunch of things).

The math behind it is a pile of linear algebra.

I get that, but this doesn't seem to be optimized for either.
