  Results are presented from numerical simulations of the flat-space nonlinear
Maxwell-Klein-Gordon equations demonstrating deep inelastic scattering of $m=1$
vortices for a range of Ginzburg-Landau (or Abelian-Higgs) parameters
($\kappa$), impact parameters ($b$), and initial velocities ($v_0$). The
threshold ($v_0^*$) of right-angle scattering is explored for head-on ($b=0$)
collisions by varying $v_0$. Solutions obey time-scaling laws, $T\propto
\alpha\ln(v_0-v_0^*) $, with $\kappa$-dependent scaling exponents, $\alpha$,
and have $v_0^*$ that appear not to have the previously reported upper bound.
The arbitrarily long-lived static intermediate attractor at criticality
($v_0=v_0^*$) is observed to be the $\kappa$-specific $m=2$ vortex solution.
Scattering angles are observed for off-axis ($b\neq 0$) collisions for a wide
range of $b$, $v_0$, and $\kappa$. It is shown that for arbitrarily small
impact parameters ($b\rightarrow 0$), the unstable %but arbitrarily long-lived
$\kappa$-dependent $m=2$ "critical" vortex is an intermediate attractor and
decays with a $\kappa$-\emph{independent} scattering angle of $135^{\circ}$, as
opposed to either of the well-known values of $180^{\circ}$ or $90^{\circ}$ for
$b=0$.
