I've tried to keep numbers out of translations as much as possible, and I'm not sure this will be a common requests for other languages.
In the meantime, if you'd like to get around this issue, you can modify the qa_post_html_fields(...) function in qa-app-format.php - look at this pair of lines:
$fields['points']=($post['points']==1) ? qa_lang_html_sub_split('main/1_point', '1', '1')
: qa_lang_html_sub_split('main/x_points', qa_html(number_format($post['points'])));
... and change to something like ...
$fields['points']=($post['points']==1) ? qa_lang_html_sub_split('main/1_point', '[YOUR PHRASE]', '1')
: qa_lang_html_sub_split('main/x_points', qa_html(number_format($post['points'])));
Where [YOUR PHRASE] is substituted as appropriate.
