What I want to do: 
  
Sort products based on price. yes there can be multi prices per item but in my case the prices[0] for all products suites my needs for ordering. 
  
What I have tried 
function compareProducts($a, $ {       return $a['pricing'][0]['price'] - $b['pricing'][0]['price']; }  $packages = usort($packages, ' compareProducts'); 
  
But this is not chaning the order.  Or can I change this in the Controler, with a order by statement as this would be the correct place to change this. 
  
Thanks
