Manually start scheduled launchd job

On our Mac OS X (10.6) Server we have setup several backup scripts that are controlled by launchd and launched at specific times. For this we have defined StartCalendarInterval and this all works very well.

Now it happens that I would like to start one of these jobs out of schedule, but this does not start the job (but also does not give an error/warning):

sudo launchctl start org.job-label

The manpage of launchtl states that start is intended to test on-demand jobs, no word of scheduled jobs. Is there a way to kickstart scheduled jobs?

Edit after getting the response: Yes, manually starting scheduled jobs also works via the launchctl start command.
