The btrfs tools package in 12.04 appears outdated and doesn't take advantage of the newer features such as scrub introduced in kernel v 3.0. How can I upgrade to a newer version? Do I need to compile from source?
I've installed the debian package from wheezy, same version is in sid. The package has the most up to date features, which I need. No system instability so far. Hope ubuntu gets it in the repository soon. Thanks for the advice.
There are some instructions for getting the latest version at btrfs wiki. There is also a bug report asking for a newer version in ubuntu bug #894456
Compile from source might be a good idea; you could also check if there is any package on the debian tree. (Look for the sid tree). In any case, trying to change a package like a fs managing package might corrupt the operating system or worse corrupt the file-system itself.
This quantal package installed on precise for me and seems to be working well:

It may or may not work for you.
