Sort Nested Object - 2 properties

Question

Hello,
I am trying to sort based on a few properties of an object. The only issue i am having is the properties are within a nested object.
For example.
I would like to stort the following object by StreetNumber and StreetName, but these properties are inside 'locations_attributes' array.
    "commute": {
        "minutes": 0,
        "startTime": "Wed May 06 22:14:12 EDT 2009",
        "locations_attributes": [
                "StreetNumber": "12",
               "StreetName": "Main"
                "StreetType": "St"   
                "StreetNumber ": "17",
               "StreetName": "Morning Side ",
                "StreetType": "Dr"
                "StreetNumber ": "26",
                "StreetName": "Blake",
                "StreetType": "St"               
Can this be done ?

Answer 1

I get a JSON result from a REST service and I have a custom component that I populate.
I am not usin a datagrid, but a extended version of the List component.
I am just trying to sort the returned result sorted by street number and street name.
I was using a compareFunction in a sort() method, but only found samples for sorting off of one field.. not 2.
Here is  is a sample of what I was using for 1 field.
private function sortByAttribute(a:Object, b:Object):Object
            var x:String = a.attributes[this._activePanel.SortField].toLowerCase();
            var y:String = b.attributes[this._activePanel.SortField].toLowerCase();
            return ((x < y) ? -1 : ((x > y) ? 1 : 0));
