Using a system of points thought up by Mekonsrock in the Tampa Bay prospect ranking, I've gone through and calculated the 'points' that each system has based on Sickels' rankings

A = 10 points

A- = 8 points

B+ = 6 points

B = 3 points

B- = 2 points

C+ = 1 point

Based on those point values, here is the current list of farm systems, assigned by points.

1. St. Louis – 68
2. Seattle - 65
3. Tampa Bay – 62
4. Texas – 61
5. Houston – 61
6. Pittsburgh – 61
7. Minnesota – 60 (Meyer – B+, Sickels ranking; May – B, based on preliminary Top 50)
8. New York NL – 59
9. San Diego - 58
10. Chicago NL – 58
11. Boston - 56
12. Miami – 55
13. Arizona – 48
14. Colorado - 44
15. Cincinnati - 43
16. San Francisco – 42
17. New York AL – 42
18. Philadelphia – 40
19. Kansas City – 38
20. Milwaukee - 37
21. Los Angeles NL - 36
22. Atlanta – 36
23. Baltimore – 36
24. Cleveland – 35
25. Toronto – 35
26. Oakland – 34
27. Washington – 33
28. Detroit – 26
29. Los Angeles AL - 24
30. Chicago AL – 23

Be warned, I tried to figure in all the prospect trades that hadn't been updated in the Top 20 posts, but I may have missed some. If you want to go through and check, please feel free.
