I thought I'd throw this in to show some things in python that make such
comparisons very easy to write and also to recommend to use the patch as key
and version as value in the dict.:
Note that the meat of the code is really about 4 lines because of (module) sets
and list comprehension. Everything else is window dressing.

===================================
# /usr/bin/env python
from sets import Set
# pretending these stripped from file
recc_ary = ["117000-05", "116272-03", "116276-01", "116278-01", "116378-02",
"116455-01", "116602-01", "116606-01"]
serv_ary = ["117000-01", "116272-02", "116272-01", "116602-02"]
# use patch as value and version as key
recc_dct = dict([x.split("-") for x in recc_ary])
serv_dct = dict([x.split("-") for x in serv_ary])
# use Set to see if patches overlap
overlap = Set(recc_dct.keys()).intersection(serv_dct.keys())
# find differences (change comparison operator to <,>,<=,>=, etc.)
diffs = [patch for patch in overlap if recc_dct[patch] != serv_dct[patch]]
# print a pretty report
for patch in diffs:
print "reccomended patch for %s (%s) is not server patch (%s)" % \
(patch, recc_dct[patch], serv_dct[patch])
