I haven't touched MySQL in quite some time but I believe the issue is that MySQL doesn't support the full data type range in the CAST() function.

I believe you would have to use CAST( value AS SIGNED ) instead of INT as you're using in your example.

The MySQL CAST() Function documentation can be found at http://dev.mysql.com/doc/refman/5.0/en/cast-functions.html#function_cast[^]
