Showing number of items per context in custom list

The default context list shows number of items for each context which I find very useful (ie available or remaining items depending on view settings). Is there a way to show this in my custom context? I don’t like to use the default list because I am unable to sort it by name. (I begin each task with a date using textexpander and I like to see the tasks by age so that I can notice if a task is getting really stale.)
