Just a heads up to say that the Ultimate 1.0.1 bug that randomises newly written Mystcraft ages now occurs on servers in Ultimate 1.0.2 & 1.1.0 (it previously only affected Single player for some reason).
Full details and workaround/"fix" here:
http://forum.feed-the-beast.com/thr...-ages-in-single-player-only-workaround.14138/
If you're having trouble getting an age to generate the way you've written it, check that link above.
I also have an issue open on the FTB helpdesk as this appears to only be a bug with the Ultimate modpack and not Mystcraft itself:
