You don't say which shell you are using. This is bash...
Code:
for (( x=9 ; x>0 ; x-- ))
do
   y=$(printf "%02d" $x)
   z=$(printf "%02d" $((x+1)))
   echo mv filename_$y.txt filename_$z.txt
done

...remove the echo if it does what you want.

On second thoughts, since the number of files is hard-coded why not just copy and paste the output from this script...
Code:
mv filename_09.txt filename_10.txt
mv filename_08.txt filename_09.txt
mv filename_07.txt filename_08.txt
mv filename_06.txt filename_07.txt
mv filename_05.txt filename_06.txt
mv filename_04.txt filename_05.txt
mv filename_03.txt filename_04.txt
mv filename_02.txt filename_03.txt
mv filename_01.txt filename_02.txt
