Synopsis:
   $sort(<list>)
   $numsort(<list>)

Technical:
   These functions sort the given list in ascending order.  The $sort()
   function sorts the list based on character value, while $numsort()
   sorts by numeric value.

Practical:
   The $sort() function is used primarily for alphabetizing the list.  It
   isn't true alphabetical order, since uppercase letters come before
   lowercase, but it works for most cases.  The $numsort() function is
   used for sorting a list of numbers.  It understands negative numbers,
   and any non-number is treated as 0 (zero).

Returns:
   the given list, sorted

Examples:
   $sort(foo bar blah erf booya)       returns "bar blah booya erf foo"
   $sort(foo Bar blah Erf booya)       returns "Bar Erf blah booya foo"
   $numsort(4 -6 34 -96 0)             returns "-96 -6 0 4 34"
   $numsort(4 -6 34 -96 0Erf blah)     returns "-96 -6 0 Erf blah 4 34"
