I actually didn´t thought of that use, but thats really evil. adding insult to injury, you waste this wizards action so he can´t counter your silence.Silence is broken in 3.5. Employed properly, it can shut down a wizard of any level who has not specifically prepared against it.
The cleric should never simply cast silence on the wizard during his turn. That's the least effective way of using the spell.
What he should do, is ready an action to cast silence on the ground at the wizard's feet when the wizard attempts to cast a spell. The wizards' spell is automatically ruined. This is strictly better than counterspelling, because it always works, and allows a low level spell to counter a high level spell.
A low level cleric can shut down a high level wizard in this fashion, for as many rounds as he has silence spells, and possibly for good if he has enough silence spells to blanket the available area. All he has to do is win initiative, or survive until his first turn (ok, so that might be difficult!), and it's over.
To make this work better: prepare many silenced spells yourself. Something against fort or ref which easily succeeds against wizards. If you are a bard I would advise grease.
