Nerdgasm, take a look in the spell_globals table, you can set a required qglobal for certain spells that you don't want to get scribed, it also requires you to set the value in which is required, the name is also nice to put in there so you can modify it later.
Code:
mysql> select * from spell_globals;
+---------+------------+-------------+-------+
| spellid | spell_name | qglobal | value |
+---------+------------+-------------+-------+
| 1 | Test | TestQGlobal | 1 |
+---------+------------+-------------+-------+
