Make the script executable, put a shebang in; #!/usr/bin/env tclsh

#!/bin/sh

. /etc/rc.subr

name=tclshexample
rcvar=tclshexample_enable

load_rc_config $name

: ${tclshexample_enable=YES}

command="/usr/local/bin/dir/script"
command_interpreter=tclsh
command_args="-D -c /usr/local/etc/conffile"

run_rc_command $@

Would be much easier if you were to provide specifics or the actual script :)
