You can't, not like this. Perl opens a shell (or a pipe) to execute the back ticks, so it's only text that goes "over the wire".

`perl myscript.pl \@arr` would actually pass a literal @arr to myscript.pl.

To pass any data structure except strings you first have to convert them to string, by serializing them.
