Delegate OmniFocus Tasks with Sparrow

Don Southard created an AppleScript that sends tasks from OmniFocus to Sparrow:

Sparrow updated a few hours ago and brought with it basic support for AppleScript. I wanted to test it out and see what they included so I whipped this very basic script to delegate a task in OmniFocus by sending an email with details about the task using Sparrow.

Very nice. How long until someone figures out a solution for the other way around? Because I would love to export Sparrow emails as OmniFocus tasks.

Update: Ben Brooks shares an updated version of the AppleScript that works with Mail.app and also embeds a link to the OmniFocus task in the message.
