For task-based scenarios it would help to see it used in a sentence.

Hope this isn't too late for what you need, but...

A cognitive walkthrough is also known as a heuristic evaluation. A usability expert uses a set of known best practices and evaluates the page/site/app against them, writing up the results. It's used when it's impractical to bring in sufficient users for a usability test of the functionality in question.

Task-based scenarios sound like what I know as use cases. The evaluator chooses a set of concrete tasks (e.g., Create an Account, Cancel an Order) and designs (or performs or usability tests) them. Working with use cases ensures that the end-to-end performance of a given task is appropriate.
