I've found Omni's cross platform support on iPad to be as absent as it can get. That being said, you might try sending the file to Omni's awesome support ninjas to see what they have to say.

Omni Outliner for iPad wasn't meant for serious outlining for document creation. There is no good way to bring outlines into Word without bringing in a lot of unnessary baggage unfortunately.

If you do find a good way to use it for outlining to writing workflow let us all know.
