No, snort can't execute scripts. It never has been able to, and never will. 
Process invokation is a fundamentaly slow process, something that would bog 
snort down for so long that it could miss thousands of packets in the interim.

Use logwatchers to execute scripts, not snort.

Flexresp enables snort to send TCP reset packets and ICMP unreachable 
messages to attempt to cause the client and/or server in a communication 
session to close the sessions and not accept further data.
