The Finder has lots of additional layers between the user and the file system--when you run commands from a shell, you are closer to the file system. Within these layers, the Finder does various types of preflight checking, validation, rolling back, and so on. Therefore, you shouldn't be surprised if the Finder is far more finicky and unforgiving.
Implement statfs() in your file system and make sure you return something reasonable. Implement chown(), chmod(), and utimens(). To begin with, you may get away by just returning success and not actually doing anything real within these calls. Don't return -ENOTSUP from xattr functions unless you want xattrs to be handled through the fallback path (that is, through "._" files). If you don't want xattrs at all, consult the man pages for xattr system calls and return the appropriate error that denies the specific call. ENOTSUP from these calls have a special meaning on Mac OS X (not just for MacFUSE, but for any file system in the kernel).
