I'm developing a Perl script that will perform certain functions based upon the time of day and day of the week. Below is a minimal test case of a piece of code that I'm working on. 
#!/usr/bin/perl -w
use strict;
my $now = 8; # we'll pretend it's between 8 and 9 PM
my @hours;
my %url = (
    monday => {
        1 => "Too early in the morning",
        3 => "Someone came home from a bender",
        7 => "Time for coffee",
        16 => "Need to slack off the last hour of work"
    }
);

# begin awkward code

@hours = reverse (sort {$a <=> $b} keys %{$url{"monday"}});
foreach (@hours) {
    $now = $_, last if $_ <= $now;
}

# end awkward code

That code will assign "7" to $now. It seems to me that there should be a more "perlish" way to extract from the hash of hashes the greatest hash key that is less than or equal to $now. Can anyone help me come up with a clear example? (On the other hand, I don't want terribly obfuscated code).
