The above bug has been closed but the documentation is now misleading again for jQuery 1.8.0 (critically, 1.5+).

The documentation reads:

error This handler is not called for cross-domain script and JSONP requests. timeout In Firefox 3.0+ only, script and JSONP requests cannot be cancelled by a timeout; the script will run even if it arrives after the timeout period. Data types When data is retrieved from remote servers (which is only possible using the script or jsonp data types), the error callbacks and global events will never be fired.
