This line:

@arry = ( $one, $two, $three );

...is creating a copy of the values stored in $one, $two, and $three. But they're just copies; the variables are in no way linked to the array itself.

You probably want to pass references to $one, $two, and $three. That way @arry would hold references to those variables, not copies of their contents:

@arry = ( \$one, \$two, \$three );
${$arry[1]}++; # Increment the referent's value.
print "two is $two\n";
print '$arry[1] is: ', $arry[1], "\n";
print '${$arry[1]} is: ', ${$arry[1]}, "\n";

See perlref, but first perlreftut.
