ActionScript 2.0 :: SortOn() Multiple Fields With Different Options?

I have an array that contains search results and looks like this:

array[x].id :Number
array[x].sectionID :Number
array[x].occur :Number
array[x].title :String
etc...

I want to sort it by sectionID ASC and occur DESC (occurances). What I read in the documentation is that I can sort on multiple fields like so:

array.sortOn(["sectionID", "occur"], options);

But I need to specify different options for each fieldName while it seems the function only allows for one set of options.
