Another possible approach would be to make a perspective that shows the tasks you want included in the email, call it "Tasks due today" or whatever suits you. This perspective can be opened by visiting the URL omnifocus:///perspective/Tasks%20due%20today and there's support in iCal to run scripts as an alarm. With a bit of tinkering, I think you could have iCal run a script that opens that perspective, uses UI scripting to issue a print command to print to a PDF file that gets handed to Mail and sent to you. You might not have to learn as much about Applescript to go this route, although that's just an off the cuff guess.
