Heh, I was just going to complain that
$list.sort didn't seem to work. I was trying to use closures to print with
Groovy, and I was having problems, but the code you've got below works
great. Thanks!!!

Re: [xwiki-users] how to
sort objects?
The velocity version won't work because the sort function is not
available.. Apparently Groovy does the magic..
I've added a sort() function to the xwiki API for the future.. In the
meantime you can use groovy
