you’ll need to set the Ultimate SEO URL rewrite rules to ignore direct client requests for the /blog folder by using an additional RewriteCond.
eg)

# Donâ?™t rewrite blog directory
RewriteCond %{REQUEST_URI} !^/blog.* [NC]
RewriteCond %{REQUEST_URI} !^/wordpress.* [NC]

# Handle all other URIs using Zen Cart (index.php)
RewriteRule (.*) /index.php?%{QUERY_STRING} [L]

# Do rewrite blog directory
RewriteRule ^blog(.*)$ /index.php?main_page=wordpress&$1 [E=VAR1:$1,QSA,L]
