Short cut processing of
Code:
if (a[$2]++ > 1 && a[$3]++ > 1 && a[$4]++ > 1

will circumvent the evaluation of a[$3] and/or a[$4] should either of the earlier comparisons fail. Try a modification of your script:
Code:
awk     'BEGIN          {FS=OFS=";"}
                        {a[$2]++;a[$3]++;a[$4]++
                         if (a[$2] > 1 && a[$3] > 1 && a[$4] > 1){print $0";ROLE 3";}
                        }
        ' file
ULLNP;78;17/09/2013;OL;ROLE 3
NPNG;14;12/09/2013;AperturaTK;ROLE 3
NP;14;12/09/2013;Controllo;ROLE 3

which is - funny enough - identical to Don Cragun's result. Sorting will in almost any case modify that result, as the order in which the lines fulfill the conditions will be scrambled.
