Steve, sorry, but I can't say that I fully understand your
description, but conditions of batch scrips tested on every
transaction in a batch, but process stops as soon as we find a match.
We don't want to fire the same scrip multiple times on the same batch.

For example batch has status, queue and two cfs change.
* If a condition fires its scrip on correspond then the scrip action
wouldn't be applied. All txns in the batch would be checked against
the condition.
* if a condition fires its scrip on queue change then the scrip action
would be applied and default transaction accessor will point to queue
change. The condition wouldn't be checked against cf changes.
* if a condition fires its scrip on any cf change then the scrip
action would be applied and default transaction accessor will point to
the first cf change. The condition wouldn't be checked against other
transacactions after the first change in a cf.

Something like that, hope it helps.
