gtk_tree_view_column_get_cell_renderers - in no particular order?

[Igor Gorbounov <igorbounov voronezh serw ru>]

Gtk doc says:
"GList*      gtk_tree_view_column_get_cell_renderers  (GtkTreeViewColumn 
*tree_column);
Returns a newly-allocated GList of all the cell renderers in the column, 
in no particular order. The list must be freed with g_list_free()."
Why in no particular order? How can I identify the render I've iterated to?
I put in a treeview cell three different renderers 
(GtkCellRendererToggle, CustomComboRenderer,
CustomSpinButtonRenderer) and I switch off some of them in particular 
situations.
So I need to understand in which order they are put into list.
