Use Zen grids with Views
You can create grids inside the main container or others.

You can look at these 2 modules for views and grids:

Views Responsive Grids

Views Column Class

Then you only need to create your own grid for that view. And of course you can select n columns with nth-child

For example: A view with Views Responsive Grids of 3 columns and N rows

  .your-view-class {
  $zen-column-count:  3;
  @include zen-grid-container();
  div:nth-child(n+1) {
    .views-column-1 { @include zen-clear(); @include zen-grid-item(1, 1);}
    .views-column-2 { @include zen-grid-item(1, 2);}
    .views-column-3 { @include zen-grid-item(1, 3);}
  }

}
