From the looks of it, you want to use the sort function and/or the reverse function.

ruby-1.9.2-p136 :009 > a = ["abc_1", "abc_11", "abc_2", "abc_3", "abc_22"]
 => ["abc_1", "abc_11", "abc_2", "abc_3", "abc_22"] 

ruby-1.9.2-p136 :010 > a.sort
 => ["abc_1", "abc_11", "abc_2", "abc_22", "abc_3"] 
ruby-1.9.2-p136 :011 > a.sort.reverse
 => ["abc_3", "abc_22", "abc_2", "abc_11", "abc_1"]
