How to sort a List based on the item's integer value

The list is like

"1"
"5"
"3"
"6"
"11"
"9"
"NUM1"
"NUM0"

The result should be like

"1"
"3"
"5"
"6"
"9"
"11"
"NUM0"
"NUM1"

is there any idea to do this using LINQ or Lambda expression?

Thanks in advance

Here is a C# 7 solution (assuming the list has the name a):

    var numericList = a.Where(i => int.TryParse(i, out _)).OrderBy(j => int.Parse(j)).ToList();
    var nonNumericList = a.Where(i => !int.TryParse(i, out _)).OrderBy(j => j).ToList();
    a.Clear();
    a.AddRange(numericList);
    a.AddRange(nonNumericList);
