In revision #5099, you have a new API: GB.CompValue().

It takes two 'GB_VARIANT_VALUE *' 'a' and 'b', and returns 1 if 'a' is 
greater than 'b', -1 if 'b' is greater than 'a', and 0 if 'a' equals 'b'.

When 'a' and 'b' do not have the same type, it tries to do its best 
(conversion if they are not objects, NULL is always the lower value, and 
object is always greater than a non-object...).
