Although you defined the value labels, it seems as if you haven't assigned the 
labels to the values.  Add the following command in between 
-label define q1 . . .- and -tabulate q1, missing-

label variable q1 q1


When I do the following, I get what you're looking for

set obs 4
generate byte q1 = 1
replace q1 = .a in 2
replace q1 = .b in 3
replace q1 = 2 in 4
label define q1 1 a1 2 a2 .a unsure .b "won't tell"
label values q1 q1            // <- it seems that you're missing this command
tabulate q1, missing

The commands above give me this:

         q1 |      Freq.     Percent        Cum.
------------+-----------------------------------
         a1 |          1       25.00       25.00
         a2 |          1       25.00       50.00
     unsure |          1       25.00       75.00
 won't tell |          1       25.00      100.00
------------+-----------------------------------
      Total |          4      100.00

Thank you for the helpful responses.  I am still
unsure on how to display the labels "unsure" and
"wont tell" for the extended missing values:

. tab q1, missing

 Question 1 |      Freq.     Percent        Cum.
------------+-----------------------------------
         a1 |          1       25.00       25.00
         a2 |          1       25.00       50.00
          . |          2       50.00      100.00
------------+-----------------------------------
      Total |          4      100.00

. list q1

     +----+
     | q1 |
     |----|
  1. | a1 |
  2. |  . |
  3. |  . |
  4. | a2 |
     +----+

Thanks!
