Here is a longer write-up of some ideas you can use to do this kind of thing in Scrivener. Note that there is actually a chain of posts linking to different discussions, that you can follow. The further back you go though, there will be differences in feature set.
For example in the past the only way to filter a folder by a label was to set up some complicated Project Search settings. Now all you have to do is switch to Outliner mode in the main editor, and hit ⌘F / Ctrl+F to access the filter settings, where Labels are one thing you can filter by. The resulting filtered list can be fully selected and opened into the same editor (Navigate ▸ Open ▸ in Editor) to make for a semi-permanent listing (as a multiple selection stored in the editor history queue), that you can switch to Scrivenings mode on.
