What map? Maybe try a different waypoint for the map. for example, the old Aztec waypoint file is no good for CS1.6 as the main route for T's has changed and the bots don't have the brain power to escape the T spawn.
Set the bots to aggressive.
Coax them along with radio commands like "taking fire need assistance" "enemy spotted". When you read the manual you'll see certain radio commands will be followed by the bots.
Check this stuff in ivpbot.cfg:
