Mailman invokes the POSTFIX_MAP_CMD command with one argument equal to
the path to the virtual-mailman file. The intent is that this will run

/usr/sbin/postmap /path/to/data/virtual-mailman

which will update virtual-mailman.db with the changed virtual-mailman.
Presumably, when you replace /usr/sbin/postmap with
/path/to/your/script, you still want virtual-mailman.db to be updated so
you need

/usr/sbin/postmap $1

somewhere in your script so when Mailman invokes

/path/to/your/script /path/to/data/virtual-mailman

The $1 inside the script is replaced with the first argument and the
script runs

/usr/sbin/postmap /path/to/data/virtual-mailman

You could of course hard code the path to virtual-mailman in the postmap
command in your script instead of using $1 to get it from the invoking
command, but the $1 is more general.

If it failed when you tested your script by hand, that is because you
didn't invoke the script with the /path/to/data/virtual-mailman argument
as Mailman does.
