You can take advantage of lambda expression in LINQ functions like OrderBy

string[] Separator = new string[] { "__" };
var sortedList = list_lines
    .OrderBy(s => int.Parse(s.Split(Separator, StringSplitOptions.None)[4]))
    .ToList();

As an unrelated side note, please use correct C# naming conventions so your code is easier to read and is unified with existing C# code-base. E.g. not beginning local variable names with capital letter (Separator -> separator) and using lower camel case (Pascal case) in case it contains more words (list_lines -> listLines)
