Help on best way to gather/sort results [Array/Hash]?

Greetings ruby fans,

I'm a greenhorn at this cool lang ruby. Much to learn. Perhaps you
chaps could help me with an issue I have. I've read through a number of
the post on sorting Arrays and Hashes. And yet I can't seem to put my
finger on the solution. I want to sort on the second column. So it
seemed from what information I gathered, that I need to gather my
results into a hash. Am I on the right track? Oh, let me tell you what
your looking at here; I am scanning each mail file in our queue for
commonalites (spammer) instead of the useless (my opinoin) qmHandle we
have for qmail. So, I've got a working prototype. If you could help me
on my sort and if you have any other comments/suggestions to throw my
way I'm sure I could learn a thing or two. Being new to ruby, there's a
lot of new ideas here. Thank guys.

Code:
#!/usr/local/bin/ruby -w
require 'find'

@results = Array.new

# Iterate through the child directories & call the parse file method
def scan_dirs
root = "/var/qmail/queue/mess"
Find.find(root) do |file|
parse_file(file)
end
@results.sort!
print_results
end

# Parse each file for the information we want
def parse_file(path)
file = path[(path.length-7), path.length]
sourceip = ""
email = ""
subject = ""
email_found = false
line_no = 0

File.open(path, 'r').each do |line|

line = line.strip # Remove any \n\r nil, etc
line_no += 1

if line_no == 1
if line.match("invoked for bounce")
# Internal Bounce Msg
sourceip = "SMTP"
end
end

if (line_no == 2 and sourceip.empty?)
if line.match("webmail.commspeed.net")
sourceip = "Webmail"
else
sourceip = line.scan(/\b(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})\b/)
if sourceip.empty?
sourceip = "No Source IP**"
end
end
end

if (line.match("SquirrelMail") and sourceip == "Webmail") or
(line.match("From:") and sourceip != "Webmail")
if email.empty?
email = get_email(line)
end
end

if line.match("Subject:") and subject.empty?
subject = truncate(line,50)
end

if line_no == 20 #Nothing more we want to read in the file
@results << ["#{file}", "#{sourceip}", "#{email}", "#{subject}"]
line_no = 0
return
end
end
end

# Truncate subject line
def truncate(string, width)
if string.length <= width
string
else
string[0, width-3] + "..."
end
end

# Print out results
def print_results
print "\e[2J\e[f"

print "Mess#".ljust(10," ")
print "Source".ljust(18," ")
print "Email Addrress".ljust(30, " ")
print "Subject".ljust(50, " ")
1.times { print "\n" }
111.times { print "-" }
1.times { print "\n" }

@results.each do |line|
print line[0].ljust(10," ")
print line[1].ljust(18," ")
print line[2].ljust(30, " ")
print line[3].ljust(50, " ")

1.times { print "\n" }
end
end

# Get email address from line/string
def get_email(line_to_parse)
# Pull the email address from the line
line_to_parse.scan(/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i).flatten
end

# Ok, begin our scan
scan_dirs
exit
