The manpage that you refer to explicitly contradicts what you say
above:

 $mode = '0644'; chmod $mode, 'foo';      # !!! sets mode to --w----r-T
 $mode = '0644'; chmod oct($mode), 'foo'; # this is better
 $mode = 0644;   chmod $mode, 'foo';      # this is best  

You only need oct() in the second case that you gave.  I mention
this only in the interest of accuracy, I don't want to start an
argument.
