Counterlash doesn't force additional costs to be paid

Describe the Bug:
Counterlash doesn't force additional costs to be paid. AI cast a Stormscape Familiar I Counterlash-ed it and chose Headless Skaab. It entered the battlefield without forcing me to exile a card from my graveyard. Same happened with Flamekin Bladewhirl in place of Headless Skaab.

Which card did behave improperly?
Counterlash

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink dev 778ccb5 version - duel

What exactly should be the correct behavior/interaction?
1/22/2011 If you cast a card “without paying its mana cost,” you can’t pay any alternative costs. You can pay additional costs, such as kicker costs. If the card has mandatory additional costs, you must pay those.

Are any other cards possibly affected by this bug?
