According to the email:
We have discovered an error in the charge to your account for your recent purchase of Plants vs Zombies from BlackBerry App World. You were charged US$6.99 and the correct price is now US$4.99. This issue has since been corrected and you will be issued a refund of $3.00 USD. Thank you for your patience.
So there you have it, a refund. Except, the dollar amount is a bit confusing. A $3 refund for a $2 discrepancy doesn't add up, so I suppose it remains to be seen how much the refund actually turns out to be. In any case, kudos to RIM and the App World Team for getting this sorted out in a timely manner.
