Ross-at-neces-dot-com already did what you're searching for. I'm using 
his periodic scripts for some months now, check here: 
http://www.neces.com/blog/technology/integrating-freebsd-zfs-and-periodic-snapshots-and-scrubs. 
They're doing all necessary stuff, like checking for scrub in progress 
too. Hope you'll find them helpful.

Cheers :)
