The problem is, Notch and Mojäng AB applied for a trademark regarding "Scrolls" and I'm guessing Bethesda is afraid that since "Elder Scrolls" contains "Scrolls" they themselves could face possible legal actions in the future regarding a trademark they've established way earlier than "Scrolls". It's a defence mechanism to prevent possible predictable issues.
If you think about it that way it all makes sense really.
