Solution
Ajax requests are event driven. Therefore, once a request receives its data, the success: function is called.
You can add the received data to an array as it comes back and then wait until the array is filled ( using if(holderArray.length = x){} or something like that ) with all the returned data to complete your task in order.
Pass the order number along to the success portion in a variable and use that to enter in and then grab the data stored in the array.
holderArray[orderNumber] = result;
