Except for the formatting, how far would this get you:
Code:
awk '
NR == FNR       {q = $1 "," $2
                 $1 = $2 = ""
                 T[q "," ++C[q]] = $0
                 next
                }
                {q = $1 "," $3
                 X = q "," ++D[q]
                 printf "%s\t",  $0
                 if (X in T)    print T[X]
                 if ($3 == "?") print "  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -"
                }
' file1 file2

Please note, that
Quote:
awk's behavior is to give precedence to the last line number in an array when one of its elements is repeated
does not quite accurately describe the situation - array elements are just overwritten when indices are encountered another time(s), and awk does this as any other programming language.
