"The SQL store, on the other hand, compiles the predicate and sort
descriptors to SQL and evaluates the result in the database itself. This is
done primarily for performance, but it means that evaluation happens in a
non-Cocoa environment, and so sort descriptors (or predicates) that rely on
Cocoa cannot work." [1]
