This will probably work:

using System;
using System.Collections.Generic;
using System.Linq;

public class Program {
    public static void Main() {
        var lista = new List<string> { "12/10", "01/02", "123/12", "A/1", "4/5" };
        var listaClassificada = lista.OrderBy(x => ConversaoParcial(x));
        listaClassificada.ToList().ForEach(Console.WriteLine);
    }
    public static string ConversaoParcial(string texto) {
        int valor;
        string textoParcial = texto.Split('/', '-')[0];
        return int.TryParse(textoParcial, out valor) ? textoParcial.PadLeft(4, '0') : textoParcial.PadLeft(4, 'A');
    }
}
