Have it this way:

Options -MultiViews
RewriteEngine On    

RewriteCond %{HTTP_HOST} ^www\. [OR]
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$
RewriteRule ^ https://%1%{REQUEST_URI} [NE,L,R=301]

# external redirect to redirect old URL to pretty URL    
RewriteCond %{THE_REQUEST} /a\.php\?slug=([^\s&]+) [NC]
RewriteRule ^ /%1? [R=301,L,NE]

RewriteCond %{THE_REQUEST} /tag\.php\?id=([^\s&]+) [NC]
RewriteRule ^ /tag/%1? [R=301,L,NE]

RewriteRule ^tag/([\w-]+)/?$ tag.php?id=$1 [L,QSA,NC]

# internal rewrite to forward to actual URL
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([\w-]+)/?$ a.php?slug=$1 [L,QSA]
