randomly order a list

I made a typo:
	delete line random_line_number of the_lines
should be
	delete line random_line_number of some_lines
(see below)
Sorry,
Michael

I want to re-order the list so that the correct answer may be the second or third word, and not necessarily the first. How can I do this successfully every time? The docs give an example like this:
>>

So then I tried randomly setting the randomSeed value, since this value is supposed to affect the random() function and the any keyword, but this didn't seem to make much difference except to change it so either the second or third word is *always* the right answer. I need it to be more mixed up than that.
