Api3 'getoptions' ordering doesn't work as JSON

Some discussion here: http://forum.civicrm.org/index.php/topic,30298
OK, so the problem is that it is literally impossible to preserve order in a JSON object.

Other api actions accept a "sequential" param which will return a javascript array rather than an object, which will preserve ordering. So I think the solution is to support this param for getoptions.
Return signature:
[

{key: 1, value: 'Female'}

,

{key: 2, value: 'Male'}

,

{key: 3, value: 'Transgender'}

]
