Perhaps you just need to sort your list of keywords. The IDL docs say:
The IDL_KW_PAR struct provides the basic specification for keyword
processing.
The IDL_KWProcessByOffset() function is passed a null-terminated array of
these
structures. IDL_KW_PAR structures specify which keywords a routine accepts,
the
attributes required of them, and the kinds of processing that should be done
to them.
IDL_KW_PAR structures must be defined in lexical order according to the
value of
the keyword field.
