While it is true that it does not specifically address Conditional discharges, this document which they brought out in October 2013 is much better than the ambiguous previous version. A lot of effort from people like Amber and a few others who pestered the home office to clarify various issues bore some fruit.
Having said this you can see the case worker guidance on Conditional discharges here..
