Because you really wanted a code review:

public int GetAccountSortByAccountCode(int account)
{
    string connStr = ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;

    // You should be able to make every SQL query a "const";
    // otherwise, you've probably missed a SQL injection vulnerability:
    const string query = "SELECT TOP 1 ac_sort_order FROM lkup_account_codes WHERE ac_code = @account";

    using (var conn = new SqlConnection(connStr))
    using (var cmd = new SqlCommand(query, conn))
    {
        cmd.Parameters.AddWithValue("@account", account);

        conn.Open();
        object commandResult = command.ExecuteScalar();

        return (commandResult == null || Convert.IsDBNull(commandResult))
            ? 0
            : Convert.ToInt32(commandResult);
    }
}
