How to order scatter graphs in a trellis

Hi all,

I'm producing a scatter graph and then trellising by row based on country name. The charts always appear in alphabetical country name order from top to bottom but I would like to order them by an integer value that is stored in a different column in the same table. Is this possible? I can't see an option anywhere. Could I write a CASE statement that would sort by the integer value but still trellis by the country name?
