Only the first element in a list of arguments is being processed by 
OptionParser.  With the following program:

-----------------------------------------------------
require 'optparse'

options = {}

optparse = OptionParser.new do |opts|
  options[:list] = nil
  opts.on("-l","--list x,y,z", Array, "Example") do |list|
    options[:list] = list
  end
end

arg = "--list a b c".split
optparse.parse(arg)
puts options

Issue #8120 has been updated by drbrain (Eric Hodel).

You must use commas and no whitespace when entering a list as in your 
second arguments to opts.on
