A good way to test your Requirements expression in your submit file is to use the "-constraint" flag to condor_status.  Just use your requirements expression as what you give to -constraint, and condor_status will limit (constrain) the output to just the machines where the expression evaluates to True.  Be careful to escape quotation marks so cmd.exe (on windows) or bash (on Linux/Mac) doesn't mess things up.

I think you can do what you want as follows by adding the following line to your submit file:

  requirements = substr(Machine,0,1)=="e" && int(substr(Machine,1,3)) <= 16

You can test it first with condor_status like so: 

  condor_status -cons "substr(Machine,0,1)==\"e\" && int(substr(Machine,1,3)) <= 16"
 
(note the quotation marks inside the expression are escaped with backslashes).

Note that the ClassAd function int() does exactly what you want... no need for $INT(), which actually is
something else.  The builtin ClassAd functions are documented in Section 4 of the HTCondor Manual
