You can not directly call the ID scripting interface from Bridge. ID exposed some of their scripting functionality via the Cross-DOM (page 181 of the Bridge Scripting Guide), but I don't think that is what you're looking for.
You can send a script designed to run in ID from Bridge to ID using BridgeTalk.
The best example of one is the Contact Sheet for InDesign script.
