OMG this is a tricky nice one!
ok in awk, when i see question about duplicate, i should think using ++


... question : in awk ---> "" + 1 = 0 ????

indeed :

Code:
# sort -t, -k2rn infile
5678,10,z
9999,10,k
5678,9,l
1234,1,y
1234,0,x
# sort -t, -k2,2rn infile | nawk -F, '{print A[$1]}'





# sort -t, -k2,2rn infile | nawk -F, '{print A[$1]++}'
