If I understand your requirements correctly, then this script should do what you want. Make sure to change the username on the first line to your username.
set username to "lizzan"
set cy to (year of (current date)) as integer
set cm to (month of (current date)) as integer
set cd to (day of (current date)) as integer
set yd to yesterday(cy, cm, cd)
set yy to item 1 of yd
set ym to item 2 of yd
set yd to item 3 of yd
set yFolder to "Macintosh HD:Users:" & username & ":Documents:To Do:" & yy & ":" & ym & ":" & yd
set cFolder to "Macintosh HD:Users:" & username & ":Documents:To Do:" & cy & ":" & cm & ":" & cd
tell application "Finder"
move every file of folder yFolder to cFolder
end tell
on yesterday(y, m, d)
set d to d - 1
if d ≤ 0 then
set m to m - 1
if m ≤ 0 then
set y to y - 1
set m to 12
end if
set thirtyones to {1, 3, 5, 7, 8, 10, 12}
set thirties to {4, 6, 9, 11}
if m is in thirtyones then
set d to 31
else if m is in thirties then
set d to 30
else if leapyear(y) then
set d to 29
else
set d to 28
end if
end if
set yd to {y, m, d}
return yd
end yesterday
on leapyear(y)
if y mod 4 is 0 then
if y mod 100 is 0 then
if y mod 400 is 0 then
return true
end if
return false
end if
return true
end if
return false
end leapyear
Caveat: The script will fail (and have moved possibly only some of your files) if there is already a file with the same name in the folder it is moving to. If you want to replace the files in that case, and avoid failing, add with replacing at the end of line 18 (move every ... to cFolder with replacing).
Edit to add: Oh, just saw that you had it set up in your Dropbox instead of in the Documents folder. Just change the paths on lines 14 and 15 to reflect the path you're using, and it should be fine.
At the top of the screen, above your action, there should be a list-box that says Service receives selected <text> in <any application>. Changing <text> to folders should give you the folders as input.

The answer depends on what version of OSX you are running.
Snow Leopard doesn't appear to store Date Added or Creation Date of files.
For Lion and later, there are a couple of ways that Google revealed:
Try the following code taken from
https://discussions.apple.com/message/23974953#23974953
Alternatively have a look at the code that uses the
mdlscommand line tool as shown herehttps://secure.macscripter.net/viewtopic.php?id=37910
Unfortunately I am running Snow Leopard and cannot test the above.
