ObjC-appscript has an AEMCodecs class that includes code for packing and
unpacking AppleScript-style records, if you don't mind embedding the Appscript
framework or extracting the classes you want by hand. (I've received a patch
from another appscript user to break out AEMCodecs and some other bits for this
sort of use, but I've been too busy recently to apply it.)

Unless the script needs to be user supplied, you could skip the NSAppleScript
bit altogether. e.g. Running the above script through ASTranslate (from the
appscript website) gives me the following raw code, which'd clean up nicely:
#import "SFGlue/SFGlue.h"
SFApplication *safari = [SFApplication applicationWithName: @"Safari"];
SFReference *ref = [[[safari documents] at: 1] name];
id result = [ref getItem];
#import "SFGlue/SFGlue.h"
SFApplication *safari = [SFApplication applicationWithName: @"Safari"];
SFReference *ref = [[[safari documents] at: 1] URL];
id result = [ref getItem];
Or there's Apple's own bridge - not as good, but I'm guessing it would work for
this.
