Using awk inside a for loop is an overkill for this task. You can use a command grouping construct for this task:
Code:
#!/bin/ksh

for i in a*.txt
do
 {
  print "CIF,"\t",Status,"\t",FirstName,"\t",LastName,"\t",BirthDate,"\t",Address,"\t",City,"\t",Province,"\t",Country,"\t",occupation,"\t",ClientSinceDate TotalBalance"
  cat "$i"
 } > "${i}.tmp"
 mv "${i}.tmp" "$i"
done

By the way I noticed that you missed do and done in your for loop.
