RFE: taskopen -s | -S <key>
-s as in sort
-S as in sort reverse

sorting is always a tall order, 
but the order in which taskopen presents a list, 
the sort-driver is important. Sort by;
id
desc
annot
label
would be a essential, and it would be great to sort on any taskwarrior field, like
project
priority
due
or "pseudo-field" like urgency or age
