Bug details

Describe the bug

servers_config.sls and nginx.snippets fail to render in v2.5.0 because of unsupported comparison between 'int' and 'str':

    Rendering SLS 'base:nginx.servers' failed: Jinja error: '<' not supported between instances of 'str' and 'int'

Steps to reproduce the bug

git checkout v2.5.0 salt state.apply nginx.config,nginx.servers

Expected behaviour

state.apply run sucessfully

Attempts to fix the bug

For me it worked with json(sort_keys=False)
