Two things that may be problems...

This will only execute more than once if the combined length of the objects is twice or more times the maximum length. This may be what you intend but I don't quite understand the logic. Is your intention to only model complete rows and leave off the last partial one?
if int (i * obj_lenght / length_max ) < 1 then
The only integers less than one are zero and negative. This is a curious way to do this. It also means that on the second row it will only execute for (approximately) half of the blocks that fit in the max length, on the third row for only a third and so on. I doubt this is your intention.
Overall I find your code a bit difficult to decipher. If I understand what you are trying to do, this is how I would go about it...
block_lg = 1.0
block_wd = 0.5
block_ht = 0.25
max_lg = 10
total_blocks = 36
number_X = INT(max_lg/block_lg)
number_Y = INT(total_blocks/number_X)
FOR i = 1 TO number_Y
FOR j = 1 TO number_X
Block block_lg, block_wd, block_ht
addx block_lg
NEXT j
del j-1
addy block_wd
NEXT i
This code skips the last partial row (as yours appears intended to do). To model the partial row you can change line 12 above to read:
FOR i = 1 TO number_Y + 1
or...
FOR i = 0 TO number_Y
Note the statement "del j-1". It seems that GDL increments the loop once more than you might expect (apparently one last time when the condition is NOT met) this makes the number of transformations one less than the final value of the increment variable ("j" in this case).
One other thing, I generally try to avoid using the "del top" statement. It's fine for simple parts, but as scripts get long it should only be used between clearly distinct sections of code that you want to absolutely share no transformations. Otherwise it is good to get in the habit of counting out and deleting just the number of transformations necessary.
