Try to put your script in the "scripts" sub-directory.

From the flower page
http://www.nongnu.org/util-vserver/doc/conf/configuration.html :

/etc/vservers/vserver-name/scripts
 
A directory for scripts. By default, when one of these scripts will be
executed, the execution of defaultscripts (within .../.defaults/scripts) will
be skipped. To execute them nevertheless, the $DONT_SKIP_DEFAULTS environment
variable must be set by one of the in-shellcontext scripts (the
non-executable ones).

post-start :
The scriptlet which will be executed after the vserver has been started.
Before executing the script, the vserver root directory will be made the
working directory.
