It doesn't work because you pass a block that accepts only one argument to 
sort. Any block passed to sort is supposed to take two arguments, compare 
these arguments and return -1, 0 or 1 depending on which argument is greater.

What you apparenty want to do would be archieved by writing
e.entries.sort.each {|file| puts file }
thus passing the block to each and not to sort.
