If you have the Mac application, you can make a context-mode perspective using the time estimates for grouping/sorting/filtering and the iPad will display it even though it will not show you the value of the estimate. I have a Quick Dash perspective, for example, which shows me all of the available actions which have estimates of 5 minutes or less, grouped by context. One could construct a perspective that grouped by context and sorted by duration estimate, showing only those with a duration, but unless you limit it to a certain duration, that doesn't seem quite so easy to use...
