I'm a pretty pessimistic sort of chap, but I would still be inclined not to 
bother with the year.  I appreciate what you're saying, but you can always 
call your schema something else if a previous domain owner happens to have 
already used the name you want to use.  The risk doesn't seem to outweigh 
the ugliness and difficulty of remembering a random number to me.  A 
definite case of YMMV though.
