You could try something like this:

1. Set up your pricing file:

code    q10
item1   5.00
item2   3.50
...etc

2. Capture the 'raw' total of your cart contents (there may even be a tag 
for this by now):

[set raw_total][/set]
[item-list]
[calc]$Scratch->{raw_total} += ([item-quantity] * [item-field price])[/calc]
[/item-list]

3. Check the raw total to see if the order qualifies, and if so, set 
another scratch variable:

[if scratch raw_total >= 2000]
         [set broker_price]pricing:q10[/set]
[else]
         [set broker_price][/set]
[/else]
[/if]

4. Set up your catalog.cfg to use the broker_price value (actually you 
would do this first, but the logic is easier to follow if I show you at the 
end):

PriceField   no_price
CommonAdjust '[scratch broker_price]', ;products:price

The scratch variable no_price will point IC to the broker quantity pricing 
entries in the pricing table only when the un-discounted total of the order 
meets the minimum, and since that number is culled from straight list 
pricing, an broker reduction will not disqualify it.

NOTE:  I did not test this particular code, but I do this kind of thing 
frequently, so it should work for you.

Good Luck!
