Ok, here's an example, it's up to you now to figure it out and fit it as desired.
And please stop bumping up and double posting questions as a loser or you'll be banned!

echo "01-JUL-2007" | 
awk 'BEGIN {
  FS=OFS="-"
  split("JAN,FEB,MAR,APR,MAY,JUN,JUL,AUG,SEP,OCT,NOV,DEC",m,",")
}
{for(i=1;i<13;i++) {
  if($0 == m){$0=sprintf("%02d", i)}}
}1'
