Scrip ordering now enforced

I just checked code for RT 3.5 into Subversion today which enforces
ordering alphanumerically by description on the scrips you run. What
this means is that you can now prepend a number (00, 07, 14, 25) to the
beginning of the description you give each scrip, and they will always
run in that order. It’s not a huge change, but it should make life
easier for people – thanks to Joby Walker for the suggestion. It
should end up part of RT 3.5.8.
