How to filter top 10 best-sellers on Stiletto theme collection page?

Sorry the code before was from collection-item.liquid

The code for main-collection-product-grid.liquid is here:

{%- liquid
  assign paginated = false
  if section.settings.pagination == 'paginated'
    assign paginated = true
  endif

  assign per_page = section.settings.rows | times: section.settings.columns
  assign filter_bar_enabled = false
  if section.settings.show_item_count or section.settings.show_sort or section.settings.show_filters
    assign filter_bar_enabled = true
  endif
-%}
