You can add ALL the items (whether checked or not) to session like this:

Session.Add("AllItems", cblScope.Items);

Or you can just add the checked ones with a bit more code:

List<ListItem> selectItems = new List<ListItem>();

foreach (ListItem item in cblScope.Items)
{
    if (item.Selected)
        selectItems.Add(item);
}

Session.Add("MySelectedItems", selectItems);
