Try this:
;Artificial Intelligence Script
;Header
desc = Stop and shake
;Triggers
:state=0,plrwithinzone=1:state=1,etimerstart
:state=1:plrfreeze=1,camshake=5
:state=1,etimergreater=1000:state=2
:state=2:destroy
;End of Script
If you want to increase the duration of the halt and shake, then change 1000 (1 second) to something higher, possibly 2000 (2 seconds). Just keep in mind that it measures milliseconds. You just need to assign this script to a triggerzone where you want it to happen.
Happy to help,
