I stand corrected. The answer provided by mhapps worked like a charm. It's the last answer. I quote him:

I had this problem, and to solve it quickly I recreated the validation summary like above and used ViewBag to store the errors in the correct order by referencing an array of ordered field names. Not particularly nice but the fastest thing I could think of at the time. Razor/MVC3.

Controller code:

List fieldOrder = new List(new string[] { 
"Firstname", "Surname", "Telephone", "Mobile", "EmailAddress" })
.Select(f => f.ToLower()).ToList();

ViewBag.SortedErrors = ModelState
   .Select(m => new { Order = fieldOrder.IndexOf(m.Key.ToLower()), Error = m.Value})
   .OrderBy(m => m.Order)
   .SelectMany(m => m.Error.Errors.Select(e => e.ErrorMessage))
   .ToArray();

Then in the view:

@if (!ViewData.ModelState.IsValid)
{
    
  
    

        @foreach (string sortedError in ViewBag.SortedErrors)
        {
            
@sortedError
 
        }
    
    
}
