Btw I can confirm that I get the same result on Windows XP TinyPerl 5.8.

My suspicion is that the answer may lie in the precedence of operators. The = seems to be evaluated first, and then the the ?: group second. Am I right?

We could confirm this by doing : $z = 1; $x = 1; $z = $x ? $z = 2 : $z *= 9; print $z;

Now, the output is not 1, it's not 9 but 18. How does it become 18? The fact that it's 18 seems to suggest that first the $z = 2 gets evaluated, and then immediately after that the $z *= 9 gets evaluated. (Note: the = sign and *= are on the same level of precedence.)

Edit: Another interesting code is $z = 1; print $z *= 2, $z *= 9; # This prints 1818 instead of 218

Edit: I thought I was onto something, but apparently not. I'm just even more lost now. I did this : 

my $A = 1;
my $B = 7; 
my $C = 5;
my $D = 0;

$D = $A ? $B *= 2 : $C *= 9;

print "A=$A B=$B C=$C D=$D";

And the output is..... :drum roll:

A=1 B=126 C=5 D=126

Okay. I give up. I'm lost! Maybe we discovered a bug? How does $B become 126? Lol
