Subject: Re: Custom Method not running

A method is called upon its receiver object.  Your method is defined
such that sort is being called upon implicit receiver 'self' (in this
context, self == Object) and passed an argument of either 'less' or
'more'.  The Object object doesn't have a method called 'sort', thus
the error message.

To sort object 'less' or 'more', you need to call sort on those objects:

less.sort + [middle] + more.sort
