WordPress Popular Posts は便利なワードプレスのプラグインで、記事を人気順に並べることが可能です。
特定のカテゴリーに含まれる記事だけを表示することはできるのですが、タグでは表示を絞る事ができません。
というか、人気記事を表示させるプラグインの、ほとんどは何故かタグで表示を絞ることはできません。

特定のタグが含まれる記事を人気順で並べるには
WordPress Popular Posts プラグインのwordpress-popular-postsの、form.php の中に追記することで実現可能です。
ちなみに修正したのはVersion: 3.3.2 です。

これで、下記のようにウィジェット内にTag(s) ID(s) という項目が出来上がります。
あとは、通常のWordPress Popular Posts設定方法でOKです。
