You can nest the singular and plural versions of the shortcode:
[gravityforms action="conditional" merge_tag="{:3}" condition="greater_than" value="10"]
[gravityform action="conditional" merge_tag="{:3}" condition="less_than" value="30"]Your value is greater than 10 less than 30[/gravityforms]
[/gravityforms]

You can use this snippet to create multiple conditions in a single shortcode:
https://gist.github.com/spivurno/9db18385ed1d1f11a897bdfa8a1f2007
[gravityforms action="conditional" relation="and"
value="{:3}" operator="greater_than" compare="10"
value2="{:3}" operator2="less_than" compare2="30"]
Your value is greater than 10 less than 30
