Ordering a List Based on Another List of Values

I have a class called Inventory, with a list of Locations that have a key of what order I want them to be sorted on. I was ASSuming a SortedList would keep the values in order by the keys, but it does not.  Below is the class and the console appplication I'm trying to test it with.
object1 should be sorted => FWBB3B,A2M4,EWM4. The list is thrown back in the same order that it is added.

public class Inventory
    {
        public string InvNumber { get; set; }
        public int Quantity { get; set; }
        public string Description { get; set; }
                
        SortedList<int,string> Location = new SortedList<int, string>();
        SortedList<int,string> LocationList = new SortedList<int,string>()
        {
             {1,"C5"},{2,"FW"},{3,"A1"},{4,"A2"},{5,"B1"},{6,"B2"},{7,"EW"},{8,"C1"},{9,"C2"},{10,"C3"},{11,"C4"},{12,"Howie"},{13,"MA"},
             {14,"D1"},{15,"D2"},{16,"D3"},{17,"D4"},{18,"D5"},{19,"E1"},{20,"E2"},{21,"F1"},{22,"F2"},{23,"GB"},{24,"G1"},{25,"G2"},
             {26,"BW"},{27,"G3"},{28,"G4"},{29,"H1"},{30,"H2"},{31,"H3"},{32,"H4"},{33,"I1"},{34,"I2"},{35,"J1"},{36,"J2"},{37,"K1"},
             {38,"K2"},{39,"L1"},{40,"L2"},{41,"L3"},{42,"L4"},{43,"M1"},{44,"M2"},{45,"M3"},{46,"M4"},{47,"N1"},{48,"N2"},{49,"N3"},
             {50,"N4"},{51,"NW"},{52,"O1"},{53,"O2"},{54,"O3"},{55,"O4"},{56,"SW"},{57,"BRP"}
        };

        public Inventory()
        {
            this.InvNumber = "";
            this.Quantity = 0;
            this.Description = "";
        }

        public Inventory(string invNumValue, string quantityValue, string locationValue, string deascriptionValue)
        {
            this.InvNumber = invNumValue;
            this.Quantity = Int16.Parse(quantityValue);
            BuildLocationList(locationValue);
            this.Description = deascriptionValue;

        }

        private void BuildLocationList(string locationValue)
        {
            string[] templocations = locationValue.Split(',');
            //SortedDictionary<int,string> tempdict = new SortedDictionary<int, string>();

            foreach (string s in templocations)
            {
                foreach (KeyValuePair<int, string> kvp in LocationList)
                {
                    if (s.Trim().StartsWith(kvp.Value))
                    {
                        Location.Add(kvp.Key, s.Trim());
                    }
                }

            }
            //Location.Sort(delegate(int x, int y) { return x.CompareTo(y); });

         }

     }
