I have used the NSNumericSearch|NSCaseInsensitiveSearch combination to get the best result. I hope somebody will save their lifetime in googeling. Check the results.

    NSArray * array =
    [NSArray
     arrayWithObjects:
        [NSDictionary dictionaryWithObject: @"C3" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"C1" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"C100" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"Z0" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"Z1000" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"M" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"m" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"M" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"m" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"1A4" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"A2" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"A12" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"B4" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"B6" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"B100" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"B1" forKey: @"sort"],
        [NSDictionary dictionaryWithObject: @"1a4" forKey: @"sort"],
         nil];

    NSSortDescriptor * descriptor =
    [NSSortDescriptor
     sortDescriptorWithKey: @"sort"
     ascending: YES
     comparator:
     ^NSComparisonResult(id obj1, id obj2)
     {
         return [obj1 compare: obj2 options: NSNumericSearch|NSCaseInsensitiveSearch];
     }];

    NSArray * sortedArray =
    [array
     sortedArrayUsingDescriptors:
     [NSArray arrayWithObject: descriptor]];

NSLog(@"Original array:");


for(NSDictionary * value in array)
    NSLog(@"%@", [value objectForKey: @"sort"]);

NSLog(@"Sorted array:");

for(NSDictionary * value in sortedArray)
    NSLog(@"%@", [value objectForKey: @"sort"]);

Result

Original array:

    C3
    C1
    C100
    Z0
    Z1000
    M
    m
    M
    m
    1A4
    A2
    A12
    B4
    B6
    B100
    B1
    1a4

Sorted array:

    1A4
    1a4
    A2
    A12
    B1
    B4
    B6
    B100
    C1
    C3
    C100
    M
    m
    M
    m
    Z0
    Z1000
