linq sorted string in array by sub string

sorry I just started learning LINQ, and I would be glad if you would say it is possible to do using Linq sort this array by ID or BonusCount

string[] res;   // {"ID,Name, BonusCount",etc}    
res = new string[] {"1, Mark, 250", "4, Ostin, 150","2, Rick K., 12","11,Robert,1"};

I would get: by id:

{"1, Mark, 250", "2, Rick K., 12", "4, Ostin, 150","11,Robert,1"};

by BonusCount:

{"11,Robert,1", "2, Rick K., 12", "4, Ostin, 150", "1, Mark, 250"};I

Is it possible? Thanks in advance!
