At my school, there are only a few classes that are different between Software Engineering and Computer Science majors. CSC students have a little more focus into theoretical computing and theory, whereas SE tends to be more practical with classes on things like the software development process.
I'm currently taking computer engineering and I really enjoy it. It is a mix of CSC and EE and unlike our CSC or SE majors, it requires taking higher level math and physics courses which are needed to analyze complicated circuits. I've grown to like developing software more, but it is valuable and interesting to learn about hardware as well.
Take whichever sounds more interesting to you, but in the long run, there isn't much of a difference. Also, you should be able to take some technical electives to learn specific skills.
It looks like jQuery versions get updated occasionally in that repo, but you'll have to check and see when 1.7 gets put in.
My recommendation would be to maintain dependency versions yourself, i.e. download the version of jQuery you want to use and //= require jquery in application.js - then grab a new version of jQuery whenever you want it updated
