you might want to replace the awk code with that below. and calling it with
awk -F[ '

/\[[[:digit:]]+\]/ {

    for (i=2; i <= NF; i++ ) {

        tmp=$i;

        sub(/\].*$/, "", tmp);

        if (int(tmp) > 10 && int(tmp) < 989 ){
            print;
            break;
        }
    }
}
'

or similar.

or at least change the /\[[[:digit:]]+\]/ {  line
