It will drag into any text editor or I'm assuming anything that accepts text. Still would be handy to be able to copy it, but this is a huge time saver.
[crarko adds: I tested this, and it works as described. I also tried it in 10.6.8, and as indicated, it does not work there. It seems to be best to click on the little calculator icon in the Spotlight menu and drag that. I used both TextEdit and BBEdit as targets for the drop.]
