Another quick script, to get my top reminders in front of me. 
(iTunes script; fuzzy clock script)
Obviously everyone has different ways of managing todos, generally I only have the most important things to act upon in the reminders app. As the touchbar can only accommodate two lines, if you have more than a few dozen todos especially across multiple lists, you may want to specify the name of a list, and only put the important todos in that one list. I also haven't yet added logic to select the next scheduled todo by time, so if you've many scheduled at different times during the day this won't be very helpful.
Recommended settings: font-size 12, black background; execute every 100 secs. I also use slightly pink text colour to differentiate and attract attention from other text down there. Polling the Reminders app seems to be very slow, so I've set it to only update every 30 mins, the disadvantage of which is naturally that once completed a todo won't disappear from your touchbar for a while. You could «set_number_variable "reminderCheck" to 0» somehow though. Also I delete my todos when completed to avoid a bloated DB. The emoji symbols don't line up terribly well, but you can always change them.
-- ▫️ unscheduled; 🔸 due today; 🔺 overdue (yesterday or older)
-- displays two reminders from all lists and preferring the highest priority; the first line prefers scheduled reminders (for today, before overdue ones) if any; the second line shows unscheduled reminders; scheduled reminders only check day (so you'll see the reminder in the morning even if scheduled for later); if multiple reminders match the one displayed is random as the reminders app does not provide its display order
set today to current date
tell application "BetterTouchTool"
if time of today is less than (get_number_variable "reminderCheck") then return
local time
set time to (time of today) + 1800 -- next check in 30 mins
if time is greater than 86400 then set time to time - 86400 -- next check tomorrow
set_number_variable "reminderCheck" to time

set item1 to {rank:11, name:""}

tell application "Reminders"
-- iterating across all lists and reminders is extremely slow so we collect the incomplete ones in a single query then iterate which is significantly faster and not too expensive (except for returning every property) as there shouldn't be many incomplete
set theReminders to properties of every reminder whose completed is false -- every reminder of list "name" whose completed is false
end tell
using terms from application "Reminders"
local rank
repeat with theReminder in theReminders

set rank to priority
if rank is 0 then set rank to 10 -- heaven knows why the default value for an unset priority is a lower integer than high priority which is 1, and low is 9
if due date is not missing value then
if due date is less than today then
if rank of item1 is 11 or day of due of item1 is not day of today or rank is less than rank of item1 then -- TODO: prefer the earliest occurring from today
