Indeed. OPTIONS is a buffer-wide keyword.

No, it isn't.

The new exporter distinguishes between subtree export (toggled with C-s
key within the dispatcher) and region export. In the old exporter, C-c @
+ export command would give you a subtree export. This is not the case
in the new exporter. You have to explicitly mention you want a subtree
export. On the other hand, you don't need to select a region beforehand.
In other words, you don't trigger a subtree export anymore with C-c @
(but it triggers a region export).

If you export a subtree in the new exporter jargon, you can override
locally #+options: line by setting top headline's :EXPORT_OPTIONS:
property to an appropriate value, e. g. :EXPORT_OPTIONS: tasks:t.

There is no such mechanism for a region export. But you can implement
a function that will remove the OPTIONS line when buffer is narrowed:

  (when (buffer-narrowed-p)
     (goto-char (point-min))
     (let ((case-fold-search t))
       (while (re-search-forward "^[ \t]*#\\+options:" nil t)
         (when (eq (org-element-type (org-element-at-point)) 'keyword)
           (delete-region (line-beginning-position)
                          (progn (forward-line) (point))))))))

Then add it to `org-export-before-parsing-hook'.
