EDIT: I was using an older version of SkylandsPlus - using the newest version fixed this issue.
I used the commands as on the page/video on Bukkit and I got this in my chat:
[03:55:26] [Client thread/INFO]: [CHAT] Starting creation of world 'skylands'...
[03:55:26] [Client thread/INFO]: [CHAT] FAILED.
then /mvtp skylands gave me this:
[03:57:12] [Client thread/INFO]: [CHAT] Multiverse does not know how to take you to skylands
/mv list shows skylands as "unloaded"
This is my console output
