A bit late, but I'm also a huge fan of Taskwarrior- and on a slightly related note, I wrote the oh-my-zsh plugin and was always a bit curious as to whether anyone actually used it. Glad to hear that at least one other person finds it useful.
I do find myself using Taskwarrior's shell mode[1] almost exclusively these days though, as it significantly cuts down on the number of keystrokes necessary to interact with my todo list. If you wrap task shell in rlwrap[2] you can still get autocompletion from within the shell.
[1] `task shell`
[2] I use 'ts' aliased to `rlwrap -i -r -C task task shell` for this
