This is the Fastest Algorithm - took me 2 mili to sort 50 items ~

static void Sort()
{
    string[] partNumbers = new string[] {"A1", "A2", "A10", "A111"};
    string[] result = partNumbers.OrderBy(x => PadNumbers(x)).ToArray();
}


public static string PadNumbers(string input)
{
        const int MAX_NUMBER_LEN = 10;

        string newInput = "";
        string currentNumber = "";
        foreach (char a in input)
        {
            if (!char.IsNumber(a))
            {
                if (currentNumber == "")
                {
                    newInput += a;
                    continue;
                }
                newInput += "0000000000000".Substring(0, MAX_NUMBER_LEN - currentNumber.Length) + currentNumber;
                currentNumber = "";
            }
            currentNumber += a;
        }
        if (currentNumber != "")
        {
            newInput += "0000000000000".Substring(0, MAX_NUMBER_LEN - currentNumber.Length) + currentNumber;
        }

        return newInput;
    }
