Great news. For foundation-5, I believe you want to use the "ui" branch of the project.
Note, jquery2 is a last resort. I wrote it, but I don't recommend using it unless you really need it :)
From what I understood, foundation-5's author is currently trying to use the jquery included with Meteor.
If he finds that doesn't work, he can make foundation-5 depend on jquery2... you shouldn't need to include it directly.
Of course, if you understand all the implications (no IE6-8, both versions of jQuery sent to the client) and specifically wanted jQuery 2, by all means, enjoy :)
