Your if statement is where things fail. Assuming that the first error in the collection is indeed the one you are looking for (it might not be).

SqlError.Number is not the value that you set in RAISERROR.

Use SqlError.Class to retrieve the severity of the error, or SqlError.State to check the state (both are -10 in your example. so difficult to tell which out you mean):

catch (SqlException ex)
{
    bResult = false;                   
    if (ex.Errors[0].Class == -10)
    {
        CommonTools.vAddToLog("bInsertNewUser", "ManageUsers", ex.Message);
        if ((savePoint != null))
            savePoint.Rollback();
    }
}
