When comparing your strings, use the NSNumericSearch option

For example, in one of my model's compare: methods, I do this:

- (NSComparisonResult)compare:(IIStudent*)anotherStudent;
{
   return [[self studentName] compare:[anotherStudent studentName]
       options:NSLiteralSearch | NSNumericSearch | NSCaseInsensitiveSearch];
}
