Can't you create a look up table of keys in another list or are they changed dynamically?

Since I need that list often I would have to keep converting the record to an NSDictionary to get the keys, an overhead my program would not tolerate. (I'm assuming here that the scripting bridge would create a new NSDictionary [or NSMutableDictionary] object every time I needed the keys.)

Examining memory usage shown by Activity Monitor, I got a ballpark figure that each instance required about 8.3K of memory. I assume a standard Obj-C empty class would be negligible in size compared to this, and if so then ASOC is requiring a great deal of overhead to support a script class.
