in reply to Adding Columns from Given Data

This gives the final result I think you want:
my @oldlist = map {chomp; $_} <DATA>; my @sorted = map {$_->[2] . " " . $_->[1]} sort {($a->[2] cmp $b->[2]) || ($b->[1] cmp $a->[1])} map { [split] } @oldlist; my @newlist = map {shift(@oldlist) . ' ' . $_} @sorted; print join "\n", @newlist; __DATA__ a1 p1 q5 a1 p1 q6 a1 p2 q4 a2 p3 q9 a2 p2 q8 a2 p2 q9

__OUTPUT__
a1 p1 q5 q4 p2
a1 p1 q6 q5 p1
a1 p2 q4 q6 p1
a2 p3 q9 q8 p2
a2 p2 q8 q9 p3
a2 p2 q9 q9 p2
HTH

Update: Forgot to mention my output is different from yours, I think it was a typo in your sample output, looking at your sample input.

    Thanks tedrek for the excellent code, I slightly modified because I like to 'sort' within account block
    my @oldlist = map {chomp; $_} <DATA>; my @sorted = map {$_->[2] . " " . $_->[1]} sort {($a->[0] cmp $b->[0]) || ($a->[2] cmp $b->[2]) || ($b->[1] cmp $a->[1])} map { [split] } @oldlist; #print join "\n", @sorted,"\n"; my @newlist = map {shift(@oldlist) . ' ' . $_} @sorted; print (join ("\t", split),"\n") for @newlist; __DATA__ a1 p1 qX5 a1 p1 q6 a1 p2 q4 a2 p3 q9 a2 p2 q8 a2 p2 q9 _OUTPUT__ a1 p1 qX5 q4 p2 a1 p1 q6 q6 p1 a1 p2 q4 qX5 p1 a2 p3 q9 q8 p2 a2 p2 q8 q9 p3 a2 p2 q9 q9 p2
    Notice that 'qX5' remains within the given block of account (a1).
