Or, you might use the solution posted as an answer by Jon Lin and rewrite it to use one RewriteCond and then set a variable as suggested in the answer by TMS.

That would look like this:

RewriteCond %{HTTPS}s ^(on(s)|offs)$
RewriteRule ^ - [env=s:%2]

RewriteCond %{HTTP_HOST} ^sub.domain.com$ [NC]
RewriteRule ^ http%{ENV:s}://sub.domain.com:2368%{REQUEST_URI} [P,QSA,L]

Or, if you prefer:

RewriteCond %{HTTPS}s ^(on(s)|offs)$
RewriteRule ^ - [env=proto:http%2]

RewriteCond %{HTTP_HOST} ^sub.domain.com$ [NC]
RewriteRule ^ %{ENV:proto}://sub.domain.com:2368%{REQUEST_URI} [P,QSA,L]
