If you don't need to literally "go to another Passage" you can accomplish what you need without needing to add a script, just using built-in Twine functionality, by displaying the text of another passage inside your current passage. Just use the "display" macro:
.. and (adding to loopernow's response) you might want to display "death" instead of the rest of the passage- so start each passage with: <<if $health eq "0">> <<display "Death">> <<else>>
Comments
<<if $health eq "0">>
<<goto "Death">>
<<endif>>
In order for the <<goto>> to work you must make a new script passage and paste this into it: "Death" can be replaced with whatever your death screen passage is called.
<<if $health eq "0">>
<<display "Death">>
<<endif>>
<<if $health eq "0">>
<<display "Death">>
<<else>>
(insert the rest of your passage here)
<<endif>>
