If you run that line through B::Deparse, you get: 
    $hour > 11 ? ($xm = 'pm') : $xm = 'am';

The ternary operator (?:) has a higher precendence than =. That's why it's getting parsed that way.

Anyway, IMO, the best way to write that would be: 

    $xm = $hour > 11 ? "pm" : "am";

No precendence problems, and it's clearer, to me. I like using ternary operators for assignment, not for executing arbitrary code. It's just a matter of personal preference, really, but in certain cases it'll keep you out of trouble. Like this one. :)
