Sure, you can do this via the agenda [1], which essentially aggregates your tasks in various ways. You would organize your tasks as headers as follows

    * some project :tag:
    ** open tasks
    *** TODO Fix widget
    a stacktrace
    [[screenshot.png]]
    *** TODO Extend screen
    some notes on xrandr
    ** tasks done
    *** DONE Profit
    some notes about making money
    more notes about how much money was made

Then you can use the agenda to show all TODO items in that project, which preserves the order you have in the Org file.
