Randomise postions

Hi Guys,
Hope you can help. My actionscript skills are pretty weak so I have attached an FLA to show you what I need.
All I want to do it randomise the postion of these 6 movieclips. I have placed a duplicate layer of movieclips below for the positions. There is also a point in the timeline (indicated by a label) to add a line of code that will activate the randomisation.
I would really appreciate help on this! Any questions please ask.
Many many thanks in advance.
