Here's another extension method that overloads the existing IncludeDirectory methods and supports searching subdirectories.

public static class BundleExtensions
{
    public static Bundle IncludeDirectory(
        this Bundle bundle,
        string directoryVirtualPath,
        string searchPattern,
        params string[] filesToExclude)
    {
        return IncludeDirectory(bundle, directoryVirtualPath, searchPattern, false, filesToExclude);
    }
    public static Bundle IncludeDirectory(
        this Bundle bundle,
        string directoryVirtualPath,
        string searchPattern,
        bool searchSubdirectories,
        params string[] filesToExclude)
    {
        var physicalPath = HttpContext.Current.Server.MapPath(directoryVirtualPath);
        return bundle.Include(Directory
            .EnumerateFiles(physicalPath, searchPattern, searchSubdirectories ? SearchOption.AllDirectories : SearchOption.TopDirectoryOnly)
            .Select(physicalFileName => physicalFileName.Replace(physicalPath, directoryVirtualPath).Replace(Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar))
            .Where(virtualFileName => !filesToExclude.Contains(virtualFileName))
            .ToArray());
    }
}
