Custom Fields with more than one option are sorted based on the geometric formula. Meaning You would do something like this:

Userfield6(Radio, Select, Checkbox it doesn't matter)
Yes(1)
No(2)
Maybe(4)
Never(8)

PHP Code:

if($userfield['field6'] & 1)
  $ans = 'Yes';
elseif($userfield['field6'] & 2)
  $ans = 'No';
elseif($userfield['field6'] & 4)
  $ans = 'Maybe';
elseif($userfield['field6'] & 8)
  $ans = 'Never'; 


This continues on each time you multiply the number by itself
so to continue it would be 1,2,4,8,16,32,64 etc..
