Negative ZOrder corrupted after save/load.

Subj. All zOrder works ok, except negative values.
Don't use -1, -2, etc values for Z for any sprites. After loading csd file again - you will get these sprites on top with biggest value instead.

The following code may help the issue or not
change the line in the end of function - (void) setupFromDictionaryRepresentation: (NSDictionary _) aDict in CSSprite.m
[self _setZOrder: [[aDict objectForKey:@"posZ"] floatValue]];
to
void (_setter)(id, SEL, NSInteger);
setter= (void (*)(id, SEL, NSInteger)) [self methodForSelector: @selector(_setZOrder:)];
setter(self, @selector(_setZOrder:), [[aDict objectForKey :@"posZ"] intValue]);

Emm, i don't think so.

Probably there's signed to unsigned cast somewhere, probably in model.

As mentioned at http://stackoverflow.com/questions/155964/what-are-best-practices-that-you-use-when-writing-objective-c-and-cocoa
In general, methods in different classes that have the same selector (the same name) must also share the same return and argument types. This constraint is imposed by the compiler to allow dynamic binding.

IN CSSprite.m file we defined:
@interface CCNode (Internal)
-(void) _setZOrder:(int) z;
@EnD
BUT in CCNode.m it is
-(void) _setZOrder:(NSInteger) z;

and I change to -(void) _setZOrder:(NSInteger) z; in CSSprite file it could work.
