You can pass a function to your expression argument and use it to parse the string to a number. Setting the 3rd parameter to true reverse the results:

$scope.results = $filter('orderBy')($scope.results, 
                             [function(a){ return parseInt(a.price); },'-added']);

See updated fiddle

Looks good, but doesnt work when sort 'price' as asc and 'added' as desc.

Sorry, you want to sort by price 'asc' and added 'desc'?

Thanks, is it possible to do desc sort using the function? i mean for string is it possible to sort desc with the function?
