If it is possible to have a plate without a number then you should check for that.

static int SortPlate(string plate)
{
    int plateNumber;
    Regex regex = new Regex(@"\d+");
    Int32.TryParse(regex.Match(plate).Value, out plateNumber);

    return plateNumber;
}

static void Main(string[] args)
{
    IEnumerable data = new List() {"SHC 111U", "SHB 22x", "SHA 5555G", "HOT STUFF"};

    var sortedList = from z in data
                     orderby SortPlate(z)
                     select z;

    foreach (string plate in sortedList)
    {
        Console.WriteLine(plate);
    }

}

If it is absolutely impossible and the end of the world would come before there could ever be a plate without numbers then this shortened form will work:

static void Main(string[] args)
{
    IEnumerable data = new List() {"SHC 111U", "SHB 22x", "SHA 5555G"};

    Regex regex = new Regex(@"\d+");
    var sortedList = from z in data
                     orderby Int32.Parse(regex.Match(z).Value)
                     select z;

    foreach (string plate in sortedList)
    {
        Console.WriteLine(plate);
    }

}
