This is the output with set -x command added:

1399

However I was able to find a working solution to my problem:

Code:

(16:48:50\[deco@S.Man)
[~/bin]$ cat orig.question 
#!/usr/bin/bash
tab=`listQpsk 40|grep -w [1-4]`
seq=1
num=4
until [[ $seq -gt $num ]];do
var="count$seq"
eval var=`echo "$tab"|grep -w $seq|awk '{print $5}'`
echo $var
seq=$(($seq+1))
done

(16:50:12\[deco@S.Man)
[~/bin]$ ./orig.question 
1194
1464
1534
1399
