How can we sort the panel result by «premium» store?

[GoogleCodeExporter]

Hi, 

I  made store locator work great with this great library butd my client would 
like for the panel tu list by «premium stores» for the found result.

So I guess it has to do with the feature liste, wich I've added a «premium» 
field for them to fill, but how can I make the side panel sort the store 
listing by the premium feature and give them a css class so they're all on top 
of the list?

thanks
