Since I was poking around looking for randomizing arcscripts this
evening, too, I thought this might do the trick, for your transects.
(Maybe more so for someone searching the list archives in the future, as
it appears to do more, and maybe less, than the script that's already
been posted. Probably handy for *designing* a sampling transect, rather
than recreating one.)

From the description:
The Point Dispersion Wizard disperses coincident points radially,
linearly, randomly within a specified radius and randomly within a
containing polygon. In addition, each dispersion pattern comes with a
set of user specified options. Dispersed points can be displayed as
graphics in the existing theme, clipped to a new theme, or dispersed in
a new theme. It was written for ArcView 3.1 using the Dialog Designer.
Be sure to study the included READ_ME.txt file as it explains the usage
of the Point Dispersion Wizard, especially as it pertains to the
randomly within a containing polygon dispersion pattern which behaves
somewhat differently than the other dispersion patterns. The random
dispersion pattern options use a prime modulus multiplicative linear
congruential generator to generate random variates from the uniform
distribution on the interval [0,1] based on Marse and Roberts (1983).
