The && and || operators come from C and have the same relative precedence as they do in C. The and && or operators have been added to Perl with much lower precedence, even lower than assignment for example, which allows them to be used as statement joiners of using the Perl die idiom for example:

open ... or die ...;

The documentation for the operators can be found in the perlop man page. Note the precedence table at the start in particular.
