I am not expert, but instead of using a spreadsheet I would like to use awk as the example shows, but I would like the DIF to be under DIF and the points under PTS, how can I accomplish this?  Also if it were possible which I do not see why not?  is how can I sort the teams by the ones higher in the table?

One way could be as follows:

script:
#!/bin/sh
gawk -f dat.awk dat
gawk -f dat2.awk dat | sort -t' ' -k8n

dat.awk:
NR==1   {print $1 "\t" $2 "\t" $3 "\t" $4 "\t" $5 "\t" $6 "\t" $7 "\t" $8;exit}

dat2.awk:
NR==1   {next}
         {print $1 "\t" $2 "\t" $3 "\t" $4 "\t" $5 "\t" $6 "\t" $5-$6 "\t" 
$2*3+$3*0+$4*1}

Result:
Team    W       L       D       GF      GA      DIF     PTS
Team4   0       6       0       5       23      -18     0
Team5   0       0       0       0       0       0       0
Team2   2       3       1       14      13      1       7
Team1   3       2       1       13      17      -4      10
Team3   6       0       0       28      13      15      18

You should also be able to set OFS to tab to eliminate the "\t" literals.
