Miguel,

I have added the ordering properties to TIBOQuery.

The way you tell IBO to turn on the horizontal dataset refinement is to use
the POS param attribute with the OrderingLinks property.

Entries used to look like this:

MYCOL=1

Now the entry will look like this:

MYCOL=ITEM=1;POS=0

ITEM has reference to the OrderingItem the OrderingLink corresponds to. POS
means the position of refinement in the refinement criteria. 0 just means to
use each character as significant criteria.
