MSP430G2231 -- LPM3 with VLOCLK running TimerA, how to set up for LPM3? (assembly program)

Hi:  I am using the MSP430G2231 and trying to go into LPM3 with wakeup by TIMER A. To put it into LPM3 I am using these commands:

MOV.B      #20h,&BCSCTL3          ;SELECT VLOCLK AS THE LOW-FREQUENCY CLOCK
BIS.W      #4h,&TACTL                   ;RESET TIMER
MOV.W      #110h,&TACTL            ;TIMER CLOCK SOURCE: ACLK, UPMODE
MOV.W      #0010h,&TACCTL0     ;COMPARE MODE; ENABLE INTERRUPT
MOV.W      #6850,&TACCR0        ;COUNT UP VALUE (0.7 SEC. WITH 12 KHZ CLK)
BIC.B       #30h,&BCSCTL1          ;MAKE SURE ACLK DIVIDE BY IS 1
BIS.W      #00D8h,SR                   ;LPM3, VLOCLK ON, CPU OFF, MASKED INTERRUPTS ENABLED
NOP

Then when the processor is to wake up from the LPM3 I am using these commands:

INTERRUPT    BIC.W #00F0h,0(SP)                       ;ON: SMCLK, DCO, OSCS, CPU
                           MOV.W #CONTINUE,2(SP)
                           RETI ;clear LPM3 mode
CONTINUE      MOV.B #00h,&BCSCTL2                  ;select DCO for MCLK, SMCLK, no dividers on MCLK or SMCLK, internal R's

Then at the end of the program the vectors for the wake up are as follows:

ORG      0FFF2h             ;timer A interrupt
DC16    INTERRUPT
ORG      0FFFCh             ;interrupt vector address
DC16    CONTINUE
ORG      0FFFEh             ; MSP430 RESET Vector
DC16     RESET ;
END

It is not working.  What am I doing wrong?

Thanks in advance for your help.

Mike.
